AFAICT, it looks like list corruption in the mutex_lock path when
trying to grab the watchdog->lock, when we're coming down from
mei_watchdog_unregister().

Is it reproducible?

Btw, this is pre -rc1 kernel so I wouldn't take any issues it has too
seriously before Linus hasn't done -rc1 at least. Testing arbitrary
points in the history is known to lead to all kinds of issues which
aren't reproducible later in my experience.

Adding a MEI guy to CC just in case.

HTH.
