ipf kernel panic after 2.6 upgrade

[Jason Pellerin <jhp@bungie.com>]

Hi,

My firewall testing box conked out over the weekend during its first live
test, dying with a kernel panic:

m_copydata null mbuf
Stopped at _Debugx04: leave

The stack trace has the call chain: m_copydata, ipllog, ipflog,
fr_check, bridge_filter, and bridge_intr.

The machine was recently upgraded from a 2.6 snapshot to real 2.6 -- and
this was also it's first real test with live traffic (a fairly saturated
T1). It's a generic Dell PII with 2 3com 3c905 cards, running
nothing but ssh, ipf for firealling and ipsec for VPN-ing.

I still have it sitting in the debugger, so if there's any other
information that might be helpful to the authors in tracking the problem
down -- or if the machine's dmesg output or ipf rules, etc, would be
helpful -- just let me know.

Thanks,
