Comme= nt # 21 on bug 10501= 8 from L.S.S. 
Another problem: When I woke up the screen, sometimes the syst=
em would have
intermittent soft lockups that made the system kind of unusable... This is
after I included the patch to the latest 4.15 kernel, 4.15.5 (4.15.5-1-MANJ=
ARO)

In journalctl I find the following phenomenon. During its sleep the error
"failed to get VBLANK" is being written every 20s.

Feb 27 11:57:29 linuxsys kernel: [drm:dm_logger_write [amdgpu]] *ERROR* Fai=
led
to get VBLANK!
Feb 27 11:57:49 linuxsys kernel: [drm:dm_logger_write [amdgpu]] *ERROR* Fai=

Feb 27 11:59:29 linuxsys kernel: [drm:dm_logger_write [amdgpu]] *ERROR* Fai=
led
to get VBLANK!
Feb 27 11:59:49 linuxsys kernel: [drm:dm_logger_write [amdgpu]] *ERROR* Fai=
led
to get VBLANK!

After I woke the screen up and I get the intermittent soft lockup issue, the
error "dc_stream_state is NULL for crtc '1'" is written multiple =
times from
either dm_vblank_get_counter or dm_crtc_get_scanoutpos every 8 or 18 second=
s,
which seemed to correspond to the lockup interval. I did not test the issue
further as the system was almost unusable due to the lockup and I had to
reboot.
