I can reproduce my crash using mtu sized pkts running only 50Mbps send + receive on 2 nics. It took over-night to do it though. Running as hard as I can with MTU packets will crash it as well, and much quicker. Interestingly enough, the tg3 NIC (netgear 302t), registered 57 deg C between the fins of it's heat sink in the 32-bit slots. Makes me wonder if my PCI bus is running too hot :P Dave says I'm wierd and no one else sees these bizarre problems, btw :) More trouble-shooting to follow this next week.
