Created attachment 142828
  --> https://bugs.freedesktop.org/attachment.cgi?id=142828&action=edit
log with drm.debug=0x4 after wake up from suspend

Glitched screen issue has been resolved (I think - Thank you very much), but
the issue with black screens still persist in amd-staging-drm-next repo synced
on 15th of December.
There is a strange output in attached syslog, amdgpu is saying that hdmi
monitor is disconnected while it's not true. It is connected and powered on,
but its look like connector doesn't see it.

Thanks,
Przemek.
