<span class="quote">> You can force a reset by reading /sys/kernel/debug/dri/0/amdgpu_gpu_reset

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 messes
up KDE / sddm and even restarting sddm it isn't enough after that (soft reboot
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.</pre>
