Created attachment 129527 [details] dmesg 4.9.8 If I shut my laptop lit it suspends, then when opening the lid and resuming I get a blank screen and am unable to get the display to work again unless I reboot. I can ssh into computer and I get displayport link errors in the attached dmesg log. This issue does not occur if I use the radeon kernel module instead of amdgpu. This seems very similar to bug 90320 but I filed this one because it is amdgpu not radeon: https://bugs.freedesktop.org/show_bug.cgi?id=90320 I've also attached the Xorg.0.log but it does not have any errors indicated. It indicates successful exit because I stopped the server over ssh and tried to restart gdm a few times which is why there are multiple displayport link status failed messages in dmesg.
