re0: watchdog timeout

Sun Feb 25 16:04:26 UTC 2007

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.

Thanks,
Stefan
