vanilla 2.6.25.13, working as a router, 4 interfaces about 100MBit/s traffic
using e1000 and tg3 ethernet drivers
it's a production machine so I basicly can't touch it now, I think
it's triggerd by ipsec tunnel because
before rolling this machine on production it was stress tested
(without the tunnel) to tune the firewall,
and there ware no BUG()'s triggerd.

tunnel is created by setkey
add 10.0.5.2 10.0.5.1 esp 0xxxx -m tunnel -E 3des-cbc ...
Tomorrow i will try to trigger it in a test environment, any pointers
how to get more info out of it?
I found this http://lists.openwall.net/netdev/2008/05/06/61 will it be ok ?

device eth21 left promiscuous mode
the funny thing is that it happens only with tcpdump active on this interface
kernel 2.6.25.17, ipsec tunnel, smal packets < 97 bytes are trigger
thiese errors, kernel runs without problems,
I observed same thing on e100 network driver
