Hi,

I recently upgraded some router/NAT devices from 2.4.25 to 2.6.17.8.  They're using VIA C3 processors and NatSemi DP83815 NICs.

Right after the upgrade I started noticing these error messages on one of the heavier-loaded boxes.  This particular box routes and does NAT for around 400 users, peaking at 6Mb/sec of throughput.

The errors were happening about every 3-5 minutes.  I statically set eth6 to 100baseTX-FD with mii-tool, and now the errors appear every few hours for 10-20 minute stretches.

I searched Google and couldn't find any insight (FYI, I'm NOT using the CIPE patches).

Any ideas?
