Similar problem here. Did a backtrace using GDB:

It's just a mutex missing the init call.

Fixed in v4.3-1638-gf0524db40 .

I am still getting this in the mutex-deadlock.txt on the latest git commit (f0524db407764aeaad4229aa7301babf05a6de79).

REASON: magic
mutex 0x7f6808001ef0 locked in: (null):0 (thread 0)
mutex 0x7f6808001ef0 other in: (null):0 (thread 0)

Update to v4.3-1642-g5dbd82807 and report the crash text again.
