There's no failure in the log. Just a warning about new_config being out of
whack
"[  737.980749] WARN_ON(intel_crtc->new_config && intel_crtc->new_config !=
&intel_crtc->config)"

It's harmless, but if you want to get rid of it you can cherry-pick
 commit 2d3d111a8f34606469e589d3491c9a64f62310b8

    drm/i915: Don't clobber crtc->new_config when nothing changes

Is there an actual failure that affects the user?
