This (or something similar) was reported before:

  help w/panic under heavy load - 5.4
  http://www.mail-archive.com/freebsd-hackers@freebsd.org/msg52452.html

  panic on ip_input, ip_len byte ordering problem?
  http://lists.freebsd.org/pipermail/freebsd-net/2009-July/022473.html

But no resolutions were posted. Maybe Max remembers?

Are you using other pfil hooks (ipfw, ipfilter, etc.)?

IP fast forwarding? divert? netgraph? dup-to?

What network interfaces are used (enc, gre, gif, fxp0)?

What checksumming support (ifconfig if)?
