Hi,

not sure if this is a know issue already, but with the 3.13 kernel I got
the warning below. There is also a jbd2_log_wait_commit() hang notice in
the log but I think it's unrelated.

I thought to drop a quick message about this, since it reminded me of
another bug with a similar backtrace. That one was a drm/i915 issue and
caused by an incorrect order of device unregistration for a parent and
its child device. The only allowed order is to first unregister any
child device and only afterwards the parent device. The opposite results
in a similar warning that I included here. For some more context see:
