I think this was a recent thread here as well as on biodarwin. First 
suggestion is to look at the switch you are connecting to -- I've often 
had duplex negotiation failure problems with Cisco, Foundry and Dell 
Powerconnect switches when working on linux systems.

You should first try to adjust your switch to disable negotiation and 
force the appropriate ports to be full-duplex. That may solve your probelm.
