wm(4) problems

[Sridhar Ayengar <ploopster%gmail.com@localhost>]

Hi.

I have an Intel Gigabit Ethernet PCI card in a machine here.  I believe 
the card is based on the i82540.  The problem is that it goes down 
periodically for no apparent reason.  After a while of the interface 
being down, I get a message which reads like "wm0: Device timeout" 
followed by some numbers.  After the error message, the interface comes 
back up.  I tried switching out the cable, but that didn't help.  My 
system configuration is:

Biostar NF325-A7 nForce3-250 Motherboard
AMD Sempron 64 3000+
2 512MB DDR400 SDRAM
nVidia Quadro 580XGL
Intel EtherExpress 1000 of some sort
HP ProCurve 1800-8G gigabit ethernet switch

If you need any more information, I will be able to provide it sometime 
this evening when I will again have access to the machine.  The machine 
is currently running NetBSD/i386 3.0, but I've been thinking about 
upgrading to amd64 4.0.  Will that help?

Any help would be greatly appreciated.  Thanks.

Peace...  Sridhar
