(In reply to Michael Meiszl from comment #4)

Yeah, in my case, using a divert(4) rule seemed to be part of a trigger
condition, and that may be related to a similar bug reported in Bug #255164,
which has a commit (652908599b6f) that addresses issues in ipfw and divert =
w/
the new unmapped mbuf feature.  I tried applying that patch, along with sev=
eral
others (Bug #254309, 703419774f86; Bug #255041, 9bacbf1ae243).  No dice.  S=
till
able to reproduce random kernel crashes (not always a "panic" -- general
protection fault this time).
