            Bug ID: 104275
           Summary: Stoney Ridge laptop display goes blank after HDMI gets
                    plugged/unplugged in extended mode.
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: kai.heng.feng@canonical.com

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.
