I can support this bug report. For my (very new) computer details see attachment (lshw.txt)
I currently use Linux xxxxx 3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:58:42 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
In /etc/default/grub I have the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"
Symptoms: without the "acpi=off" parameter the computer used to reboot
repeatedly. With "acpi=off" it boots OK, but reboots spontaneously
after shutdown, and the computer must be powered off using the power
switch.
Trying the most recent upstream kernel ( 3.12.28, I guess compiled 9th
of september) the computer boots OK, even without "acpi=off" and but
during shutdown, after showing 2 red dots of the 5, first time. The
computer has to be switched off using the power button. So another
behaviour, but still it is not OK.
I also tried a LiveCD with Ubuntu 12.04.1 (Precise), this was quite OK (only no sound, on this very new hardware)
Same with LiveDVD with Ubuntu 12.4.5 (Precise, the latest), this behaved same as the 14.4.1 LiveDVD
So the bug entered somewher between Ubuntu 12.04.1 and 12.04.5
Hope this helps, adding 50% to the people affected ...
Greetings,
Jaap Woldringh
