Hello, I'm trying to make a bridge between a Broadcom BCM5703 gigabit ethernet and a sun happy meal fastethernet interface. The sunhme card supports hw checksums (and cannot be turned off in the driver). I applied the patch (to set CHECKSUM_NONE on forwarded packets), but I still get kernel oopses (though it seems less often than before). I cannot tell exactly what triggers it, sometimes it seems a large ping, sometimes a broadcast ping, sometimes just normal network traffic.

My machine survived a ping -s 2000 -f <broadcastaddr> ;). 2.4.22 crashed instantly from this command :). -- Madarasz Gergely gorgo@thunderchild.debian.net gorgo@linux.rulez.org It's practically impossible to look at a penguin and feel angry.
