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 amdg=
pu.

This seems very similar to bug 90320 but I filed this one beca=
use it is amdgpu
not radeon:
https://bugs.freedesktop.org/show_bug.c=
gi?id=3D90320

I've also attached the Xorg.0.log but it does not have any errors indicated=
.=20
It indicates successful exit because I stopped the server over ssh and trie=
d to
restart gdm a few times which is why there are multiple displayport link st=
atus
failed messages in dmesg.
