I noticed that too since some time. System doesn't hibernate and xorg
causes 100% cpu load.
Process with 100% cpu load was
/usr/lib/xorg-server/Xorg :0 -seat seat0 -auth /run/lightdm/root:0
-nolisten tcp vt7 -novtswitch
I have the same problem since several months. Suspend to disk causes a
blank screen (as supposed to happen) and then freezes the system with
100% cpu load. However, no useful log messages could be found, so I
dropped the issue.
Happens on my desktop machine, no matter how I initiate the hibernation.
(pm-hibernate, systemctl hibernate, echo "disk" > /sys/power/state)
