Looking at ifconfig for eth0:
RX packets:5829 errors:3863 dropped:0 overruns:0 frame:2169

The bad frames would appear to be a key. The nic may have a bad buffer of 
something. Is there a switch at the other end, you could try a different port 
in case the switch port is sending bad frames. 

Do you have a different machine to try the 'bad' nic in? (or another nic to 
try in that box)?
