            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.=20

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* display=
port
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* display=
port
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 short=
ly
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.
