SubjectRe: [NFS] [BUG] Onboard Ethernet Pro 100 on a SMP box: a very strange errors
Hi Denis,
I bought a Intel STL2 mobo based machine a few years ago. I'm not sure
what the network controller on it is, as it is turned off. I had a
problem where the card works fine until it gets loaded. Then things went
pear shaped. There was a bios upgrade to fix this problem. I never
installed the bios patch as I had spare network cards.
You may find that you are just reaching the point where the card fails to
work correctly.

Hope this helps,
Dave.
