No, running at slower speeds (50Mbps), the packet count was well over 4 billion (ie it successfully wrapped 32-bits). At higher speeds, it crashes before the 32-bit wrap, generally. It also does not coorelate to bytes-sent/received, or anything else that I could think of to look at. > > > >>Interestingly enough, the tg3 NIC (netgear 302t), registered 57 deg C between >>the fins of it's heat sink in the 32-bit slots.

As Dave mentioned, tg3 locks up almost immediately (like within 30 seconds), and in the meantime, it's spitting out errors that are 'impossible'. The messages I sent a day or two ago. I may have cooked my cards, or something like that, because one of the tg3's do not work in my other machine now. Still trouble-shooting that one.
