[Bug 339] Kernel panic on bridged packet

Is this bug forgotten ?
Anyhow, I ran into it when setting up this strange network of mine.. I dont
think my setup is causing anything strange however.. It appears even if no
machine is connected to the "inner" port of the bridge..
I havn't done any real testing, yet, just tried to set it up properly and
wait
for the internet to trigg the bug.
Im using a 2-port bridge for firewalling (i'll try some brouting like stuff
too,
but it's not there yet)
Panic output:
Unable to handle kernel NULL pointer dereference at virtual address 0000000c

(some iptables-rules including conntracking are added too; the usual ones
matching state related,established, and some filtering using the

Dosmas - if you would like assistance, please try to reproduce this without
tainting the kernel with the binary nvidia modules (and trying it on 2.6.17
wouldn't hurt either)
