It might or might not be related, but since network interface problems
are on topic, I also experienced issues with re(4) on both netbsd-6 and
-current; the details can be found in PR kern/45928.  There is nothing
in that driver that pretends to be MPSAFE though, and I've not found
mismatched spl(9) calls when I audited it the other day.
