Public bug reported:

Originally I thought the system had crashed when logging in or shutdown.
But it turns out it's hanging for about 60-90 seconds. When shutting
down system will reboot instead.

lsb_release -rd
Description: Ubuntu 18.04 LTS
Release: 18.04

uname -a
Linux bridge 4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Clean install.
Shutting down system reboots instead.
Suspends does not stay suspended.
Login and shutdown hangs for a long time (60-90 seconds)


Seeing these in logs.
