from Pablo Estigarribia
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?
