[Bug 1488719] [NEW] dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"

[Alexander List]

Public bug reported:

On a recent intel NUC using i915 graphics, I get the following errors in
dmesg:

[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied
(SDE)!

There are two monitors connected to this box, one with mini-HDMI->HDMI,
one with mini-DP->HDMI cable.

This happens on a new NUC, with

CPU0: Intel(R) Core(TM) i7-5557U CPU @ 3.10GHz (fam: 06, model: 3d,
stepping: 04)

I'm running a 4K display off the miniDP port.

It happens almost every single time I walk away from the computer within
10-15 minutes.

Also getting this error sporadically, only with an external monitor, on
the Dell XPS-13 developer edition (ships w/ ubuntu) on either 5.04 with
3.18 kernel or 5.10 beta with 4.2 kernel. Appears to be some kind of
buffer overrun triggered by certain intensive tasks.

Getting this error as well on a Dell XPS-13 developer edition (ubuntu
14.04 LTE) with Kernel 4.3.0-rc2 from mainline[1].

Error occurs when I connect an external monitor on DisplayPort with
4k/60hz: Monitor flickers, turns black every five seconds and turns off
completely after two or three minutes.

Error message (constantly with dmesg)

[14142.692434] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!
...

After changing resolution back to 1920x1080 everything works fine again without any error messages.
Reproducable with stock kernel on ubuntu (3.13.0-37).

I've just started getting this after updating to linux-
image-3.19.0-30-generic from linux-image-3.19.0-28-generic.

NUC 5i3RYH connected via the mini-hdmi port to a 720p tv.

100% repeatable for me using Kodi 15.1. If I play a video I get audio,
but the video is all black. If I activate the on-screen display items
they render fine, but the video content itself is missing. Audio is
fine.

Entering and exiting a video I get this each time:

[ 29.275053] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!
[ 29.275763] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!
[ 29.316539] sound hdaudioC0D0: HDMI: ELD buf size is 0, force 128
[ 29.316579] sound hdaudioC0D0: HDMI: invalid ELD data byte 0
[ 29.348980] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!
[ 29.363813] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!

Always the first six lines, sometimes more of the (SDE!) lines follow.
Always one set when playback begins, and another when playback ends.

Further to this, if I disable VAAPI acceleration in Kodi, the video
playback works again, but the kernel messages still appear.

Both the black-video and the messages are completely new in 3.19.0-30 -
haven't seen either in earlier kernels.

I can verify that I also am getting this error now that I am running
3.19.0-30 on Intel NUC5i7RYH with Iris 6100 graphics.

I don't know what the error means, but definitely getting it. Upon
update now my boot screen doesn't properly load and I have to decrypt
the disk with nothing on the screen, clear regression from 3.19.0-28,
but not sure if it's related.

Outputting ***@60 works fine, outputting ***@60 produces no

When removing the onelink prodock and connecting the dp cable directly
to the laptop then all resolutions works (***@60).

Whenever running xrandr it adds 36 lines to kernel log of 'The master

When 4k resolution is working, these error message is still present in

When 4k resolution is working, these error message is still present in
kernel.log. Maybe resolution issue is unrelated to IRQ issue

Please file that as a separate bug to not conflate this one, thanks.

I have Lenovo Thinkpad L450 with Intel HD Graphics 5500 and I can
confirm the issue is present in the mainline kernel 4.3.0-040300rc. I
did not have real noticeable issue - I just see the error messages in
the log. It can be reproduced by executing xrandr while an external
monitor is connected to the laptop. Any time I execute it, it will
produce the error messages. Also connecting the external monitor to DP2
(analog VGA) will produce the error messages in dmesg.

When there is only laptop screen on and no external display connected,
it looks executing xrandr will not produce the errors.

The problem is present in 3.19.0-30 but it is not present in 3.19.0-15.
I tried also 3.19.0-28, but using this kernel, my external monitor and even my external USB mouse and keyboard did not work.

Maybe I don't get it, but: Is the fix only shutting up the kernel
messages or is this fixing the cause?

I'm expiriencing this messages on a Lenovo T450 (20BX011GE) running
15.10 with 4.2.0-16-generic kernel. I see this messages wether external
monitor is connected or not, although with much higher frequency with
external monitor connected (dp via dock).

It seems like this messages is related to random GDM crashes. I tried to
reproduce this behaviour, but I've got no clue when this is happening so
far. I will try to investigate this further.

Got this error in my dmesg, and gets daily KDM crashes.

Have an Asus X555L with 2 external monitors connected,
each morning when i get back to the computer, the laptop screen dosn't start,
and I have no working window managment => I can use the active window, but can't change active window.

Also, if i activate the wireless-card, I can see the si (software interupt) in top raise to 100%, and then I lose all controll.
And all I found so far is this error message 1836 times in the dmesg-log

I get this error on my new Toshiba P50t-C-104, with kernel 4.3. No
monitors attached, just the default laptop screen. I get a black screen
after this message on boot. The only way to boot is to use the
'nomodeset' kernel parameter, but that dissables the intel graphics
card.

I'm still getting this on 4.2.0-17-generic with a Lenovo W550s.
Moreover, [if you read the patch](http://www.spinics.net/lists/intel-
gfx/msg78796.html) you'll see it just affects whether it prints the
warning, and doesn't correct the underlying problem. Related or not, I'm
also seeing the blank-screen symptoms [reported
here](https://github.com/NixOS/nixpkgs/issues/9755).

I'm running an T450s with 2 external DELL monitors, one 24" and a DELL
27", both are connected by Displayport.

After locking the desktop by windows+L key and returning after some time (minutes) the 27" DELL isn't working anymore and i have to reconfigure the whole display settings, the dmesg output bring up the following lines:

Running dell latitude E5450 with nVidea card and seeing this - both the error and sometimes when unlocking screen the monitor keeps flashing on and off every 5 seconds until you change the resolution and change it back.
The best way to do this is CTRL+ALT+F6 then CTRL+ALT+F7

I am also seeing the issue where X is not showing the docked monitors
(eDP) as active if I:

suspend -> undock -> resume -> suspend dock -> resume

apport is reporting crashes frequently (using the non free Nvidea driver
so I assumed this was the issue).

The bit of information I can add is that apparently Windows users are
effected by the screen flashing also (in a company so everyone has the
same laptop)!

Dell released a BIOS update to fix the flashing, but it didn't help.
Just wanted to add this as it may be a firmware issue.

Had it happen today for the first time. Other than Ubuntu updates no
changes to the configuration in months so it seems to be a very recent
change. The last time I used the dual monitor config was 5 days ago,
with no troubles at all. Now the 2nd monitor (4k) goes blank and comes
back about every 5 seconds. Tried resetting display resolution (and
then back again) and may have helped for now.

Latest Dell XPS13 dev edition running Ubuntu 15.04.

[Yuri Ribeiro Sucupira]

This bug also affects me. Well, now it doesn't anymore, because I've
downgraded my system kernel.

Device: notebook Dell Inspiron 5548

Operating system: 64-bit XUbuntu Linux 14.04

Processor: Intel Core i7-5500U

Video: dual chip. These are the two display controllers:
- Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260] display controller 33000000Hz (requires kernel module / device driver "fglrx"); and
- Intel Corporation Broadwell-U Integrated Graphics VGA compatible controller 33000000Hz (requires kernel module / device driver "i915").

Problem: the message "[drm:gen8_irq_handler [i915_bpo]] *ERROR* The
master control interrupt lied (SDE)!" floods my dmesg, and from time to
time my system crashes and my computer powers off. If I 'cat
/var/log/kern.log |grep -i i915' i see a huge amount of messages exactly
like this one, hence I can only assume that the kernel module i915_bpo
is buggy (or these kernels are buggy while they interact with that
kernel module). My notebook is subtly powering off from time to time
(unrelated with overheat, I'm pretty sure 'coz I've already monitored
temperature parameters and also 'coz I'm using a cooling laptop
base/pad, besides the fact that my notebook is brand-new: only 1 week
old).

Kernels I've tested which have this issue:
- 3.19.0-18-generic
- 3.19.0-23-generic
- 3.19.0-28-generic
- 3.19.0-33-generic
- 4.2.0-18-generic

All of them have the same problem: the kernel module "i915.ko" (in
4.2.0-18-generic) and the kernel module "i915_bpo.ko" (in kernels
3.19.0-??-generic) randomly cause subtle system shutdown (halt /
poweroff) in my notebook.

Solution: I downgraded to kernel 3.13.0-36-generic, which isn't buggy
with its "i915_bdw.ko" (version 3.0) kernel object (module). Full path
for this module:
/lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko

Notes:
- "bdw" stands for "Broadwell"
- "bpo", I believe, stands for "backport"

IMO, this bug is pretty serious and is taking a lot of time to get
fixed: my notebook could get damaged if it kept subtly powering off
several times a day, on an everyday basis, like it was doing because of
this bug. Hence, my strong suggestion to those who are experiencing this
issue is to downgrade to a stable kernel version (I recommend kernel
3.13.0-36-generic).

If you don't want to downgrade your kernel: become root ('sudo su'),
then open '/etc/default/grub' for edition (e.g. 'gedit
/etc/default/grub'), then add the 'nomodeset' option to
"GRUB_CMDLINE_LINUX_DEFAULT=" (e.g.
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"), then save the file, exit the
text editor and, still as root, run the command 'update-grub && telinit
6'. Your GRUB will be updated and your system will be restarted. After
that you won't be able to see OpenGL graphics anymore (e.g. Xscreensaver
openGL screensavers won't load), but your system will stop subtly
powering off.

True @Tom i'm running Ubuntu 15.10 also on a Lenovo T450s (20BX000TGE -
BIOS 1.16) and have these issues.

Since upgrading to Kernel 4.2.0-19-generic i can't remember that the
screen issue has occured again...both external displays are working as
expected.

I only see this issue:

[ 14.334606] [drm:gen8_irq_handler [i915]] *ERROR* The master control
interrupt lied (SDE)!

sometimes after a fresh boot inside dmesg.

I see the same error message when I try the following:

* laptop is in docking station, external monitor is connected
* send laptop to sleep
* undock laptop
* wake laptop up

The error message is present on the terminal, my KDE session is logged out. Nothing useful in .xsession-errors though.
The laptop is a new T450s, running Kubuntu 15.10.

When connecting my Lenovo T450s to the dock, the screen gets black after logging in and I have the same error message:
[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

This is with Ubuntu 15.10 and Kernel 4.2.0-19.
Updating to 4.4.0-rc4 didn't help. The problem remained.

Downgrading to 3.13 worked though: The error message is gone and the
external screen works again.

So I have this issue as well.

X1 carbon 2015 (broadwell) i5 5200U.

For me this happens without any external monitor, the system just crashes/freezes at random.
[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

I have tried the following kernels:

4.2.0-18
4.2.5
4.3.3

It would seem as this is an upstream issue, am I correct?

@joakimkoed Yes this seems to be an upstream issue, see (updated)
related freedesktop bug above, with no (working) fix released yet.

I can confirm the behaviour with an without connected external monitor
(already confirmed for 4.2. 0-16 genirc, can also confirm for
4.3.3-040303-generic).

Hmm, I'm wondering if we're handling this correctly, and if that could
cause the issue:

"For each bit, the IIR can store a second pending interrupt if two or
more of the same interrupt conditions occur before the first condition
is cleared. Upon clearing the interrupt, the IIR bit will momentarily go
low, then return high to indicate there is another interrupt pending.
Only the rising edge of the PCH Display interrupt will cause the North
Display IIR (DEIIR) PCH Display Interrupt event bit to be set, so all
PCH Display Interrupts, including back to back interrupts, must be
cleared here before a new PCH Display Interrupt can cause the DEIIR to
be set."

Oh, but the whole point of the patch ( drm/i915: Handle HPD when it has actually occurred) was to disallaow writing to PCH_PORT_HOTPLUG register when the HPD did not occur.
And this shows stable HPD with SKL for me and was inline with other interrupts handling.

Do these "[drm:gen8_irq_handler [i915]] *ERROR* The master control
interrupt lied (SDE)!" messages have any effect on HPD?

Are the status bits actually showing long/short pulses when this

Maybe we can just do something like this:

Is there any downsides to this for new-ish broadwell machines? Stuff

Sorry for spam.

I can confirm 3.13 is okay regarding this issue. Not really a good
kernel for broadwell laptops, since some FN-keys don't work etc. but it
will do for exam tomorrow :)

Hello.

Just wanted to let you know (if you were unaware) this bug does also make the system freeze randomly. I have tried to figure out what triggers it, but it seems just random. If anything it happens after 2-3 hours of activity and then 2-5 mins idle?

On kernel 3.13 it works.

Please feel free to ask me to test fixes if you need. I can compile
myself (with a patch) or I can test a kernel you compile.

Hope its okay to write here as a non-dev.

I see this bug on Ubuntu Gnome 15.10 with standard kernel only
(4.2.0-22-generic at time of writing) with intel microcode active from
additional drivers. The only freezes I have noticed appear to be
connected to a bug in asus_nb_wmi so are unlikey to help in this case.

I had to give a presentation with my laptop recently which has the same
issue of having the second screen randomly turn black and then back on
again.

Interestingly the presentation went without a hickup.

The thing that was different, was that I am having the issue when the
secondary screen was connected through HDMi ( with a minidisplay to HDMI
adaptor).

I wasn't having the issue using a mini display to VGA connector to a
projector with a far lower resolution as my secondary screen.

Want to mention that I am hit by this problem too.

Downgraded to 3.13.0-74 did not work out because hit by another
different problem which shows up in 3.13.0-74, ie when wake up from
suspend, the display got messed up. The display will not be restored
correctly.

We now know the problem is in 3.16, 3.19, 4.2 etc. No need to keep
reporting that :)

Please check if 4.4RC7 works, thats helps more.

A bit more contex:

I run lubuntu 5.10 with 4.4.0 RC7 now and it still happens. Quickly
reproducable when doing in-home streaming to my lubuntu client. The
stream (h264 decoding) crashes quite rapidly, and the typical dmesg
output is present.

Tested 4.4.0 RC7 on Thinkpad T450s with i7-5600U. Error is still present
like before, the log message is present with and without ext. display
connected, although still much higher frequency of log msgs with ext.

Just testet RC7 again.

I do not get any errors before I put in HDMI cable. Before I got error
messages even without cable, now it only happens with cable. So
something got better, but just not good enough :)

I have to revice my comment from January 4th. The error is gone without
external display connected with 4.4.0 rc7 for me too, still occuring
with ext. display connected. I'm not sure what I was looking at, maybe
booted the wrong kernel, stupid me.

Since yesterday 4.4.0 rc8 is released, same behaviour without external
display connected, error is gone. I will check rc8 with external display
connected later this day when I'm at home.

Also tested Kernel 4.4 RC8 => the same error appears in /var/log/syslog when i connect my laptop to the tv with a hdmi cable.
The error appears only at the moment when i plug the hdmi cable. Then it stops.
Then i change the configuration of the sound to hdmi display port. And the same error occurs at the moment i changed the sound configuration. see dmesg in attachment.

Just tested 4.4.0-040400rc8-generic (4.4.0 RC8).

Still get the [drm:gen8_irq_handler [i915]] *ERROR* The master control

See attached file for my dmesg output after login.

I've just rebooted with kernel 4.4.0-040400rc8 as well and also continue
to see the 'interrupt lied' line. The situation has improved though.

Quick summary, just ask if you want more details/logs.

System information: HP EliteBook, Ubuntu 15.10, i7-5600U, Broadwell-U
Integrated Graphics (rev 09)

Previously with the stock Ubuntu 15.10 kernel I was unable to attach a
second display unless I connected the display before startup / early in
the boot process and closed the laptop lid. Attaching a display over
displaylink worked fine in that case. Attaching it over VGA limited me
to 1024x768 resolution. Setting modelines for higher resolutions through
xrandr resulted in an unusable desktop.

Currently with 4.4.0-040400rc8 I'm able to attach my VGA display after
the desktop environment is running and use the second screen to extend
the desktop. Setting a different modeline still results in an unusable
desktop. I haven't had the opportunity to test a displaylink display
since installing this kernel.

Thanks for progressing on this issue.

Hi, I am also plagued by this very annoying bug.

I am running Ubuntu 16.04

kernel 4.3.0-7-generic #18-Ubuntu SMP Tue Jan 19 15:46:45 UTC 2016
x86_64 x86_64 x86_64 GNU/Linux

on a Dell XPS 13 9343

This particular laptop has a mini DisplayPort output which I connected
to a DisplayPort MST hub. The DisplayPort outputs from this hub are
connected with DP to HDMI cables to 3 full HD monitors.

My dmesg shows lots of: [drm:gen8_irq_handler [i915]] *ERROR* The master
control interrupt lied (SDE)!

I also see in the kernel log:

As a consequence, my monitors randomly turn black and on again for about
half a second to a full second. This happens in no particular order,
sometimes only one is exhibiting this behavior, sometimes two at the
same time, sometimes they do it a lot and at other times just once in a
while. But when they start to flicker, I noticed it especially happens
with the monitor that is currently focused.

Now the really interesting thing I have noticed is that this only
happens when my monitors are at the 1920 x 1080 resolution. If I switch
to 1280 x 1024, this never ever happens.

Hope this makes things a bit clearer for somebody out there.

Yes this patch is in the mainline kernel v4.5-rc1-wily. But I think
regarding our problem here it does only what it says: shut up the
messages. I just tested it, got a

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun

at boot time now (related:
https://bugzilla.kernel.org/show_bug.cgi?id=95461), while the

[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied
(SDE)!

are gone. With external monitor connected things getting worse, gdm
isn't able to use the monitor correctly and crashes from time to time.
Looks like there are now other i915 bugs (maybe regression?) more
urgent. Personally I will stick to 4.4 until I've got time to
investigate this further with a clean install of ubuntu to eliminate the
possibility that I'm looking at completely unrelated issues here.

Quick test with Kernel 4.5 RC1 connected hdmi for a few seconds => the

fine :-).

I also just tried the 4.5.0-040500rc1-generic kernel.

Minidisplay to hdmi convertor.

If I put my secondary screen on 3840x2160, I notice that after awhile I
get the same black screen interval bug again.

Keeping the resolution to the same as my laptop ( 1920x1080 ) seems to
be stable so far. No flicker yet.

This bug is causing dual monitor problem for me as well. It looks like
it was registered a long ago, when can I track if it gets fixed? It is
quite annoying that there are two options: either use laptop's display
only or use laggy open drivers...

Reproduced in: DELL INSPIRON 5749

I would appreciate any advice.

Thank you.

I have that message with a HP EliteBook 850 G2 and docking station under
kernel 3.19.0-49-generic on Xubuntu 14.04. I think it causes an issue
with unrecognised external monitor. I have attached the syslog while
reproducing via following steps:

0. directly after boot: external display is not recognised even it's connected to connected docking station (USB works fine)
1. disconnect docking station (line 1)
1. connect docking station (line 7)
2. activate external display (line 788)
3. deactivate external display (1407)
4. external display is not recognised again (USB works fine)

Maybe this is helpfull for fixing.

From Comment #48
If you don't want to downgrade your kernel: become root ('sudo su'),
then open '/etc/default/grub' for edition (e.g. 'gedit /etc/default/grub'),
then add the 'nomodeset' option to "GRUB_CMDLINE_LINUX_DEFAULT="
(e.g. GRUB_CMDLINE_LINUX_DEFAULT="nomodeset")

I've got a ChromeBook that boots with "i915.modeset=1" kernel
parameter. I'm just mentioning it for completeness.

For more or the modeset option, see
http://unix.stackexchange.com/questions/110573/what-
is-i915-modeset-1-for .

I'm not sure, but sometimes you can cheat with your system.

Example:

1.) working with your dual monitor
2.) lock your desktop (windows key and l for example)
3.) you see both external monitors locked
4.) wait sometime and they go to power safe mode
5.) coming back, press a key and see that only one monitor is available...the other one is still in power safe mode
6.) press STRG+ALT and 2 (or 3 or any other number with a terminal assigned)
7.) see a lot of drm:gen8_irq_handler error messages
8.) wait a moment and the other monitor which was/is in power safe mode will power up and showing up the same errors
9.) now yo back to your graphical UI (most of times STRG+ALT + 7)
10.) you might see that both screens are working again in dual mode...

I did this now for a lot of times (because setting the display settings
up again sucks)

From Comment #124
... I did this now for a lot of times (because setting the display

settings up again sucks)

I had luck with the following. It removed all of the dmesg's except one:

$ uname -a
Linux qotom 3.19.0-49-generic ...

$ sudo lspci | grep -is vga
00:02.0 VGA compatible controller: Intel Corporation
Broadwell-U Integrated Graphics (rev 09)

And then use the "00:02.0":

$ sudo cat /etc/rc.local
#!/bin/sh -e
# ...
# By default this script does nothing.

setpci -s 00:02.0 F4.B=30

exit 0

This is a mysterious bug affecting a LOT of machines. As I suggested at
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1520040, as a
temporary workaround I recommend downgrading to kernel
"3.13.0-36-generic".

Try it out and see if it is of any help.

Installing linux-firmware_1.156 from http://ubuntu-master.mirror.tudos.de/ubuntu/pool/main/l/linux-firmware/ didn't help. The problems seems to be when loading gnome. The execution hangs up after:

Exact same error message in brand new Dell Latitude e5550 (Intel HD 5500), BUT:
1) No external monitors
2) The laptop won't BOOT, execution hangs up.

Both in 4.2.0-27 amd64 and 4.2.0-16 amd64.
After some reboots it will hang up at
"Started Gnome Display Manager"

Booting in recovery mode I find in dmesg:
"snd_hda_intel 0000:00:03:0: failed to add i915 component master (-19)"

Installing 4.5-rc4-wily gives me:
"possible missing firmware /lib/firmware/i915/skl_guc_ver4.bin for module 915"
and booting it
"error parsing PCC subspaces from PCCT"
