   Nate,
 
   do you run any additional network modules: ipfw, pf, netgraph,
 accept filters, etc? How your system differes from a default
 installation?
 
   Is it possible for you to run with INVARIANTS option in the kernel?
 The option adds additional debugging, thus hurts system performance,
 but with it we can obtain a more informative crashdump.
