Created attachment 135429 [details] dmesg of a suspend/resume cycle. When resuming from suspend on my Asus GL702ZC the internal eDP screen does not turn back on, neither does the backlight. External screens (normal DP) are not affected and continue working. I'm running 4.14.0 on this machine. My kernel .config is here in case that is helpful: https://notabug.org/hp/linux-gl702zc/src/master/.config I see the following errors in dmesg: [ 1667.119776] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* displayport link status failed [ 1667.119785] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* clock recovery failed [ 1667.687497] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* displayport link status failed [ 1667.687505] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* clock recovery failed When using drm-next-dc the screen does turn on but the system crashes shortly afterwards. I have not been able to get any meaningful debugging data out of that configuration yet. Attached is the full dmesg of the system.
