Ahh, later in that thread there's another totally unrelated oops in
debug_mutex_add_waiter().

I'd guess that it is really wild pointer corrupting memory, quite possibly
due to a double free or something like that. Alan - it would be good to
run with DEBUG_PAGE_ALLOC and SLUB debugging etc if you don't already do
that?
