Chuq could obviously say more about this, but in general a whole lot
changed about UVM between 1.4 and 1.5 that could well change how
everything interacts with pmap making what was okay in it before
panic-causing.

I don't know the details, but the pmap is definitely not code
isolated from UVM enough (nor should it be) to mean that changes in
UVM don't tickle it in bad ways.
