dmesg1
It does not happen always, but usually after a few hibernate/resume cycles (2
or 3, sometimes earlier). The following messages can be found in dmesg (see
attachment for full output).

[ 1013.788868] [drm:radeon_vce_ib_test] *ERROR* radeon: fence wait failed
(-35).
[ 1013.788874] [drm:radeon_ib_ring_tests] *ERROR* radeon: failed testing IB on
ring 7 (-35).
After that, if the machine hibernates and resumes once again, additional errors
will be printed and the X session becomes unusable (only the cursor blinking on
the terminal). I will attach the dmesg of this too, though it might be less
interesting.
