I'm getting the occasional watchdog timeout from my re0: <RealTek 8169SB/8110SB Single-chip Gigabit Ethernet> port 0xda00-0xdaff mem 0xdfcfd000-0xdfcfd0ff irq 18 at device 10.0 on pci1 It seems to happen more frequently if I put more traffic on it. I see this with both largish amounts of either TCP (scp) or UDP (NFS), largish being around 20 Mbit/s. Not sure if the direction of the traffic matters. The card's connected to a cheap 8 port 10/100 switch. Board is a DFI 915GM-MIGF with a Celeron M processor, the controller is onboard. I think it got worse since I updated from a January 28 kernel to a February 17 kernel. Anything I could enable/look at to determine the cause? I've got a serial console and debugger on this box.
