I'd be suspecting a hardware problem. Are you sure the power supply isn't overloaded, or in need of replacement?

Nov 18 11:43:15 synapse b44: eth0: Link is up at 100 Mbps, full duplex. Nov 18 11:43:15 synapse b44: eth0: Flow control is on for TX and on for RX. Nov 18 11:43:19 synapse b44: eth0: Link is down. Nov 18 11:43:21 synapse b44: eth0: Link is up at 100 Mbps, full duplex. Link keeps going up and down, as long as there's data movment from the SATA drive, and a network movement (network download doesn't have to be saving to the sata drive) I've disabled APCI, problem persits. Steps to reproduce: 1. copy data to Sata drive CONNECTED to PCI controller 2. Download file from network via onboard LAN, doesn't matter which drive you save it 3. Onboards lan "link" goes up and down, causing disruption to network useage. ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
