This looks like a defected card. Speciaclly when you have collisions in a FULL-DUBLEX environment thats in normal operation impossible. My guess is that the interface driver (hardware) on one of the NICS is defected and generates unwanted signals and/or drops signals (wich is more likely for the carrier error). Try exchanging one of the crads with another. If it still happens swap the digital cards and you will find the true defected card. Raymond entr0py wrote: > What are "carrier" errors (from ifconfig)?
