This happens on 30 different hosts. Using the same kernel I get varying
uptime of "hasn't crashed since the upgrade to 2.6.16" to "crashes every
day". All are Tyan S2882D boards w/ integrated Tigon3. The trace I
posted to this thread indicate tg3, but in many other traces I have the
trace doesn't include any driver calls. They all panic in ipt_do_table.
I would have pasted the others, but I didn't save the System.map for
either of them and they are all pretty similar.

Here is another that just crashed:
