Created attachment 128632 [details] git-show-7155b05 Not sure it helps: The merge base 7155b057c61e55eed27bf478ac9b8034c4c97582 is bad. This means the bug has been fixed between 7155b057c61e55eed27bf478ac9b8034c4c97582 and [982bb302fdc49f8331f29103ff1c111645598d23].

I'm not 100% sure I understand what you mean here. Is the merge commit the *first* bad commit? Also, commit 982bb302fdc49f8331f29103ff1c111645598d23 doesn't exist anymore. Can you reproduce the bug with drm-intel-next-queued (instead of drm-tip)?
Yes, this is why it does not help. This was the result of git bisect after only 3 iterations (comment 5), I will provide a new result ww04.
We moved to drm-intel-next-queued and used EZBench. EZBench does not provide a bisect result, conclusion is the test result is unstable. It tested commits b403c8f, 7155b05, 2ec4584, f03ee46, 0b47a6b.
