Heh.
Yeah. Looking at it now, I can see why my patch was wrong. That mutex
is supposed to get initialized in videobuf_queue_sg_init(). But we also
can't use the lock until after it's initialized. This bug was
introduced in:
commit c37db91fd0d42d27141b6c49b768070df29e1c5e

I'm taking off for the weekend, so I won't be able to look at this
more until Monday. See you then. :)
