Can you try bisecting this one?

Jesse Barnes, Intel Open Source Technology Center
I can't bisect. I tried to bisect other other bug but with some commits
I can't even boot, kernel hangs in panic.

You can try and use 'git bisect visualize' which will show you all
commits not yet eliminated from the bisection search. There you can
choose another commit to test (or just do a git reset --hard
[thatcommit]) or look for a fix to that problem higher up in the
commit list.

I assume both of those are separate issues, but they continue in any case.
