[Bug 103700] Displayport link status failed on resume from suspend on eDP on RX580 with Asus GL702ZC
https://bugs.freedesktop.org/show_bug.cgi?id=103700
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 Reporter: hp@tmm.cx
Created attachment 135429 --> https://bugs.freedesktop.org/attachment.cgi?id=135429&action=edit 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.

--- Comment #1 from Hein-Pieter van Braam hp@tmm.cx --- I forgot to mention: I run Fedora 27 in userspace with Xorg.
The following package versions may be relevant:
xorg-x11-server-Xorg-1.19.5-1.fc27.x86_64 xorg-x11-drv-amdgpu-1.3.0-3.fc27.x86_64 mesa-dri-drivers-17.2.4-1.fc27.x86_64 libdrm-2.4.85-1.fc27.x86_64

--- Comment #2 from dwagner jb5sgc1n.nya@20mm.eu --- This bug could be the same as https://bugs.freedesktop.org/show_bug.cgi?id=103277 - but since I have only one display connected to the GPU - which stays off after resume (and then the system crashes so no other way to look at dmesg output) - I had no chance to see error messages like the ones you reported.

--- Comment #3 from Harry Wentland harry.wentland@amd.com --- dwagner, these are different issue. This one was reported on a kernel without DC, the other with DC.
