Hm, that's not what I expected to happen... I suspect this is stack
corruption, with the result being slightly different every time. Can
you see if this patch fixes the panic?

This patch did not fix the problem. But disabling CONFIG_PROVE_LOCKING seems
to avoid this problem. Since "git log 4898b99c261efe32...e6f3faa734a00c60"
range includes lockdep changes, this might be a lockdep problem.

Maybe there is a bug in completion and/or crossrelease handling?

On second thought, I don't think that's the right fix. But I do think
what you're seeing is related to a lockdep issue:
https://lkml.kernel.org/r/20171003140634.r2jzujgl62ox4uzh@wfg-t540p.sh.intel.com
I'm not sure yet why it's breaking the unwinder so badly though.

Oh, very likely. That commit is in "git log 4898b99c261efe32...e6f3faa734a00c60" range.
