For a test, I tried doing

sudo cat /sys/kernel/debug/dri/1/amdgpu_gpu_reset

during normal desktop operation (in this setup it's card 1), and it just me=
sses
up KDE / sddm and even restarting sddm it isn't enough after that (soft reb=
oot
was enough).

Then I tested it after the The Witcher 3 freeze above (remotely, over ssh).
That caused complete hang, that even ssh stopped working. So that required =
hard
reboot.
