ok, so it could be one of those two changes then.

though, I looked at the two dumps you provided, and in both cases,
the reason for the crash isn't obvious from the dump.  in both dumps,
we took a pagefault trap while storing into kernel memory that was
validly mapped according to the pmap data.  maybe it's another problem
with TLB invalidation going awry somehow?
