<pre>Everything works fine disabling dpm on amdgpu.
Workaround steps:
edit /etc/default/grub
add amdgpu.dpm=0 to GRUB_CMDLINE_LINUX=
generate new config:
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
reboot (to test new permanent config is done.
You will notice now
/sys/class/drm/card0/device/power_dpm_force_performance_level doesn't exist.
For months I though the problem was somewhere else, and was looking for many
combinations without success, without this workaround I had a very annoying
experience working, playing videos, whatever, because randomly I had freezed
display and had to restart. I couldn't play any game before, now tested with
many games and everything is perfect.
Could be good to apply this workaround by default? so users doesn't experience
the annoying bug?</pre>
