CentOS - Jan 2008 - System drops off network after a few minutes

I have an Intel SE7525RP2 motherboard with a Yukon Marvel (82541GB controller)
NIC in it. After installing CentOS 5.1 it functions fine for some minutes then
looses network connectivity. By coincidence, I was using the system to clean
some HD's for another and had booted off Knoppix and noticed it never
exhibited this behavior, the network remained functional even overnight when I
returned to the system?

I looked through messages and didn't see anything NIC/network related, can
anyone suggest something to check?

Thanks!

Hi Joseph,
When the network drops, how do you wake it up again?
That might lead us somewhere.

if it literally drops in a few minutes, run wireshark and leave it 
capturing all traffic on the LAN interface until it craps. then stop the 
capture, and look at the last set of packets.

Given my limited Linux experience, I just reboot :)
I know, not very helpful, sorry...

Also it might help to do an modinfo of the actual module that is used to
drive the NIC and see what the version is on both OSes.

I'd do a simple ifconfig first. Networking can be restarted with
"service
network restart".
