--- Comment #3 from Michael Stenzel mastergizmo@arcor.de --- Hello,
I have the same problem with an rx480. Also think it gets triggered when monitor goes into dpms "off" state. Sometimes I keep vlc running etc so monitor does not go into sleep, than the issue never happens.
says gpu load 100% under /sys/kernel/debug/dri/0/amdgpu_pm_info but I only have chrome open with 1 tab and hexchat nothing else.
System: mesa-13.0.1, xf86-video-amdgpu-1.2.0, xorg-1.19.0 kernel 4.8.13 (slackware64-current), GPU: xfx 480 gtr
