dmesg of case failed

I realized that this case (igt/kms_flip/bcs-flip-vs-modeset) was first added in
nightly test On September 4th,but first failed on October 6th.
But I can't find a good commit on both drm-intel-fixes branch and
drm-intel-next-queued branch.
If there is anything I can do to help,please let me know.
