SubjectInvalid Operand in 2.0.30

Warning Very Long so as to try and send all needed information.

This happened after a 'smurf' attack on a test win95 host.
It is on the same 100B-T as the target.
(smurf is a ICMP DOS attack by spoofing a ping to a broadcast address)
(named after a post on bugtraq)
only patch is squid file descriptor increase patch.
I blame this on the eth0 card, but I read that you all want all
oopses and such posted so here it is.

The crash happened when I tried to ifconfig eth0 down

I also got many of these in my log right before the crash:

The NIC is buggy so says the driver:

eth0: 3Com 3c905 Boomerang 100baseTx at 0xff00, 00:60:08:19:98:01, IRQ 9
8K word-wide RAM 3:5 Rx:Tx split, autoselect/MII interface.
Rx Pacing bug exists, disabling bus-master receives.
eth0: Overriding PCI latency timer (CFLT) setting of 32, new value is 248.
