Dmesg-output

Similar to bug 105018, but instead of kernel =
panic, system freezes for some
time after waking screen up.

Tested on ArchLinux, it can be reproduced on Linux 4.18 and 4.19, using an =
AMD
RX550.
It always happens when using DPMS/Screen blanking, after leaving the screen
blank for some minutes and waking it up.
It keeps freezing for some time, sometimes for seconds others for minutes.

The attached dmesg output is similar to bug 105018.=20
Every time the system is frozen, those 2 lines are shown:
"[drm:dm_crtc_get_scanoutpos [amdgpu]] *ERROR* dc_stream_state is NULL=
 for crtc
'1'!
[ 1701.356720] [drm:dm_vblank_get_counter [amdgpu]] *ERROR* dc_stream_state=
 is
NULL for crtc '1'!"

Tried removing xf86-video-amdgpu (DDX Driver), and while the freezes disapp=
ear,
it takes longer to wake up the screen and dmesg only shows "[amdgpu]] =
*ERROR*
Failed to get VBLANK!" several times.
