Obvious question: does it happen with 2.6.17.x or 2.6.18-rc5?

Most recent kernel where this bug did not occur:
Distribution:
Hardware Environment: P4 3.4G   1G Mem
Software Environment: FC3 Kernel 2.6.16.1
Problem Description: 

kernel BUG at net/ipv4/netfilter/ip_conntrack_proto_tcp.c:911!

This can only happen if something corrupts the packet, probably
within the bridge netfilter code. This patch from Stephen (rediffed
against 2.6.16) fixes such a corruption, please try if it helps.
