Public bug reported:

I get frequent, but not always reproducible "hang" after waking from
suspend

The hang often occurs before any login or password screen appears. and
cannot be broken by ctrl-alt-del or ctrl-alt-1 or any other key
combination.

Sometimes the gdm login screen is shown, but the mouse freezes, the
keyboard gets no response. The power key also has no effect. I have to
disconnect from power to reboot.

The last time I got an error message, which read:
...
Kernel panic - not syncing: Fatal exception in interrupt.
Kernel offset 0x0 from 0xffffffff81000000 (reallocation range 0xffffffff80000000-0xffffffffbfffffff)
drm_kms_helper: panic occured, switching back to text console
