O.K. So that means the problem wasn't recently introduced.

The specific set of lines I'm looks something like this: eth0: Tigon3 [partno(BCM95722) rev a200] (PCI Express) MAC address 00:10:18:15:16:b6 eth0: attached PHY is 5722/5756 (10/100/1000Base-T Ethernet) (WireSpeed[1]) eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] TSOcap[1] ^^^^^^ eth0: dma_rwctrl[76180000] dma_mask[64-bit] Like Michael, I'm tempted to look into the cabling too. How long are they? Silly question, but are they Cat5e?
