<pre>Just a random:
[ 60.264167] [drm:intel_dp_set_signal_levels] Using signal levels 00000000
[ 60.270946] [drm:drm_dp_dpcd_access] too many retries, giving up
[ 60.270947] [drm:intel_dp_start_link_train] *ERROR* failed to enable link
training
[ 60.275600] [drm:intel_dp_set_signal_levels] Using signal levels 00000000
[ 60.282323] [drm:drm_dp_dpcd_access] too many retries, giving up
[ 60.282324] [drm:intel_dp_complete_link_train] *ERROR* failed to update link
training
and no further mode changes after that to reset the screen. (Failure on our
part to propagate the error and a failure to never try again.)
If it is deterministic, that would be very useful for debugging.</pre>
