dmesg with errors and trace

This one may be hard to reproduce for some as it seems to rely a bit on cpu=
freq
ondemand being a bit rubbish on my old cpu. Lowest is 800MHz for me (high 3=
.4
GHz).

I don't use a compositing desktop and vids played in my browser (seamonkey)
don't get vsync.

Turning on TearFree gets me vsync, but while testing I got a screen lock. S=
eems
to involve timing luck - I couldn't reproduce with the browser in a sane
timescale so invented a different test that could run while AFK.

mpv -fs --vo=3Dx11 a720p60video --loop=3Dinf

Will usually lock in < 15 minutes with cpufreq ondemand.

It was still going after an hour with cpufreq set to perf.

Also seems OK with amdgpu.dc=3D0 on same kernel =3D amd-staging-4.9

As I've only recently started running DC, and never tried this test before,=
 I
have no idea whether it ever worked.

xserver is latest release ddx is git.

dmesg attached shows errors and a trace starting with

[ 2009.442985] [drm:drm_atomic_helper_commit_cleanup_done [drm_kms_helper]]
*ERROR* [CRTC:39:crtc-0] flip_done timed out
