This sounds like a buggy driver or a broken PHY.

I'm not sure what to think of your add-in NIC; you haven't stated 
make/model/driver.  You also haven't provided the complete output to 
ifconfig, complete contents of your configuration files, or any relevant 
system messages.

We are pretty much flying blind at this point.
