I've been able to reproduce the problem with PCI em copper and fiber cards. The copper cards were gigabit, but were set to 100Mbits. I have not tested with the onboard bge nics or the intel fxp cards. Since you've experienced the problem with bge I won't even bother testing them. We thought initially that the problem might be with the card. But since it's appeard with nics from 2 different vendors, 3 different cards and 2 drivers, then the cards seem less likely to be the primary culprit. We did have another problem with the tyan K8SR board that was related to the bios. When the machine was cold booted, memory performance was 25-50% of the performance when warm booted. This was fixed by a bios update (2.05v). maybe there is some other bios related memory bug that is the cause of the panics. It seems that other people have had this happen with single core machines, but I haven't been able to reproduce it on our single core machines, only on the dual-core. - Rob Watt
