Thanks.

Several of the crashes have a stack that looks like this:

  (gdb) where
  #0  0x07f00000 in ?? ()
  #1  0xc0457b6f in cpu_reboot ()
  #2  0xc03c24d8 in panic ()
  #3  0xc03d6269 in m_copydata ()
  #4  0xc01a02d8 in pf_route ()
  #5  0xc01a0ecb in pf_test ()
  #6  0xc01ac5fe in pfil4_wrapper ()
  #7  0xc041d8ea in pfil_run_hooks ()
  #8  0xc012bef3 in ip_output ()
  #9  0xc0124ce2 in icmp_send ()
  #10 0xc0124aab in icmp_reflect ()
  #11 0xc01247ab in icmp_input ()
  #12 0xc0125d27 in ip_input ()
  #13 0xc0125756 in ipintr ()
  #14 0xc0102cf9 in Xsoftnet ()

I'm probably doing this wrong but, it looks like the request needs 0x28 bytes
and only finds 0x24 before exhausting what's available?

I guess it could be a bit twiddling problem?  Clues on what to follow up
on are appreciated.
