Public bug reported:
I've got msi gp62m 7rex leopard pro laptop. Previously i was running
ubuntu 16.04 on it, then i decided to upgrade to 18.04. I installed
ubuntu 18.04 on ssd+hdd (/ on ssd, /home on hdd, ssd luks+lvm, hdd
luks). Then i installed nvidia-384 drivers and cinnamon. Everything
worked fine, but one day it just stopped powering off when shutting
down, rebooting bug or suspending. I fully reinstalled ubuntu (note:
image was downloaded after the bug started to occur), but the bug still
persists - not powering off. I tried another kernel - 4.13, i tried
running ubuntu in software rendering mode, using integrated graphics
instead of nvidia, stopping display manager before shutting down,
updating and resetting everything, including bios, but no luck. I tried
adding acpi=force in /etc/default/grub, removing 'quiet splash' -
nothing changed.
When shutting down or rebooting it stops at:
All filesystems unmounted
Deactivating swaps
All swaps deactivated
Detaching loop devices
All loop devices detached
Detaching DM devices
kvm: exiting hardware virtualization
When suspending:
Suspending console(s) (use no_console_suspend to debug)
This also occurs on the live image.
On boot it shows this messages related to acpi:
