Another pmap related panic

[Mark Tinguely]

It could be a memory problem. Could you also please apply an assert
to pmap_enter_quick() + INVARIANTS. This is a quick test that checks
all the other paths that call pmap_enter_quick() are locked out so
that two processors cannot be using the PADDR1/PMAP1 at the same time.
