I've been getting a strange issue, where traffic over one of the built in skge
nics in my server will just die. No traffic can make it over, but it'll claim
the device is up:

I should make a quick correction, the skge adapter is not built in, rather its 
a plain old D-Link GbE pci card. If it happens again, I'll try one of my 
spares (bought several D-Link cards prior to upgrading all my hardware, so 
most of them are redundant now, as the boards all have GbE built in).

If anyone else knows what might be the cause, please let me know.
