While doing so, can you enable at least some debugging?
wlandebug +state
or even better
wlandebug 0xffffffff

It smells like that something is poking the SW bmiss handler while not
in RUN state and therefore you're hitting a KASSERT(). Question is if
the bmiss timer isn't stopped/drained somewhere or if there is too
excessive call.
