            Bug ID: 103700
           Summary: Displayport link status failed on resume from suspend
                    on eDP on RX580 with Asus GL702ZC
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

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.
