I would suggest that this might be Drakino's problem, as well. The fact that you have errors (which should never occur in a properly functioning network) only on the RX side of that one interface would tend to indicate that the device that that interface is connected to isn't functioning properly. You might want to try forcing 100Mbps/FD on both that device and on your interface and see if that clears things up.

Of course, this is just a guess.
