If this is the case, then i can't reliably trust autonegotiation.  Another
problem I have had is that when using options=12 to force 100 full duplex,
the connection still is only coming up 10 half duplex.  This is cured when
I allow autonegotiation.  Am I using the incorrect option?

I will try this if/when it occurs again to see.  I have only unloaded and
reloaded the module to cure it so far.

On an unrelated note, I still seem to be getting ...

eth0: Transmit error, Tx status register 82.
eth0: Transmit error, Tx status register 82.
eth0: Transmit error, Tx status register 82.
eth0: Transmit error, Tx status register 82.
eth0: Transmit error, Tx status register 82.
eth0: Transmit error, Tx status register 82.
eth0: Transmit error, Tx status register 82.

over and over and over agina on my high traffic servers.  Is this a
problem?  

Thanks,
