<pre>Hi,
We are enabling a new Stoney Ridge laptop.
The issue can be reproduced on branch drm-next-4.16-wip and
amd-staging-drm-next.
Reproduce steps:
1. Plug HDMI monitor.
2. Change to extended mode.
3. Unplug the HDMI monitor
4. Plug the HDMI monitor
Internal display may go blank in step 3.
The internal display may also go blank in step 4. The external one shows
desktop correctly though.
I can see lots of message flooding once I plugged HDMI:
[ 120.933668] amdgpu 0000:00:01.0: 0000000030e07f1f pin failed
[ 120.933859] [drm:amdgpu_crtc_page_flip_target [amdgpu]] *ERROR* failed to
pin new abo buffer before flip
These messages stop as soon as the HDMI is unplugged.</pre>
