bisect.log
Did a bisect but got quite some skips due to the system not finishing booting.
# git bisect skip | tee -a ~/bisect02.log
There are only 'skip'ped commits left to test.
The first bad commit could be any of:

I couldn't really make sense of your bisect log, it doesn't have any good/bad
commits in it.
And I don't see how reverting a merge of v5.7-rc7 can be helping, because you
said v5.7 is good, and that contains v5.7-rc7.
Can you attach the output of "git bisect log".

Yea sorry, my fault... I thought e.g. with "git bisect bad | tee -a
~/bisect.log" bisect.log generated via tee would have the same output as with
"git bisect log" but I was wrong.
Please find the correct one attached now. I had to restart the bisect as I
already resetted the original one.
