2.6.24-rc6 oops in net_tx_action

[linux]

Kernel is 2.6.24-rc6 + linuxpps patches, which are all to the serial
port driver.

2.6.23 was known stable.  I haven't tested earlier 2.6.24 releases.
I think it happened once before; I got a black-screen lockup with
keyboard LEDs blinking, but that was with X running so I couldn't see a
console oops.  But given that I installed 2.6.24-rc6 about 24 hours ago,
that's a disturbing pattern.

(N.B. I was pretty careful, but the following was transcribed by hand.)

Kernel panic - not syncing: Fatal exception in interrupt


Network config is a little complex; there are 5 physical network
interfaces and a bunch of netfilter rules.  A quad-port 100baseT Tulip
card which provides "outside-facing" interfaces (two uplinks, a DMZ,
and a spare), and a gigabit VIA velocity card for the internal network.

The hardware has ECC memory (1 GB, kernel starts at 2.75G) and mirrored
drives, and has generally been very stable for a long time, modulo some
disk hiccups.

The tulip drivers have been solid forever.  The VIA velocity driver is more
suspect; I made an effort a while ago to get tagged VLANs working on it,
which was a notable failure.  Still, this oops is in core network code.

As you might guess, it makes people somewhat grumpy when the main
firewall/router takes a dive, but I can experiment after hours.
