Hi All,
I can't boot Peach-pi (exynos5800) with v4.6-rc-1, board hangs while
booting with below boot hang-task.
I have not git-bisected yet, will do that, but AFAIR it was booting fine
with v4.5.
Any idea?

Yeah... start with bisect. :) Beside that try booting with lockdep
enabled, because it might detect it earlier and report more data.
If this is the only stalled CPU then maybe a mutex_unlock is missing
somewhere in the cros_ec driver? (you have the backtrace...). Otherwise
you should get more backtraces from other CPUs (use sysrq to get them
eventually) which might point deadlocked locks.
Anyway most of traces here point cros_ec, so you might narrow the bisecting.
Best regards,
Krzysztof

That's correct, I can confirm that I needed Heiko's fix to boot v4.6-rc1 on
my Peach Pi a few weeks ago. I don't have my machine at hand now to test but
that fix made it to -rc3 so I would suggest using that tag instead of -rc1.

That's correct, I can confirm that I needed Heiko's fix to boot v4.6-rc1 on

that fix made it to -rc3 so I would suggest using that tag instead of -rc1.
