<pre>After resuming from hibernation (aka suspend to disk), the GPU always hangs and
get's reset.
When using Xorg, the process caught in the hang is always systemd-logind .
Under Xorg, after the GPU is reset, gnome-shell dies and get's restarted. Xorg
itself does not crash, so no graphical app crashes and the session continues
normally. I have experienced no artifacts afterwards, the system works normally
and hibernate again (to the same results) or suspend to ram (without incident).
When using Wayland, the process caught in the hang is always gnome-shell
itself. After resume, it crashes with the message "intel_do_flush_locked
failed: Input/output error". As shell dies, applications love their connection
to the wayland compositor and the session is eventually finished. Logging again
from GDM works fine and the system can hibernate or suspend, just as under
Xorg.
Suspend-to-ram works without any incident. The gang occurs *only* after
resuming from disk.</pre>
