I have a cluster of 10 machines. ifconfig on 5 of them show a very high number of RX overruns. The machines are similar, but I have noticed that the 5 that are having problems all have an "a2" version of the Nvidia MCP61 ethernet controller. The 5 that don't have problems are all version "a1".

lshw shows I'm running version 0.64 of the forcedeth driver. The nvidia drivers page shows a version 1.21 available.

Where should I go from here? I'm hoping a driver update might fix, but I cannot find a newer driver version I can install with my meager linux skills.

ifconfig:
