Dave - I've also seen this on four of our API CS20 and moving to a non-MP
kernel has stablized them for the most part (there is another issue I'm
working at getting more info about, but its not MP related).

There is a patch for pmap which may help you out.. .but from what I've ready
from private emails, MP is still considered experimental.
