This Tx state usually indicates a transceiver misconfiguration.

Does this implementation really support Home-PNA?
How old is this motherboard?
I'm guessing that this is really a slight corruption of the EEPROM table.

This message is OK -- most 21143 implementations do not interrupt on MII
link change.

This message is not.

The tulip driver assumes SYM mode and emulates a MII transceiver at
address #32 if a MII transceiver is not found.  Physical MII
transceivers are at addresses 0-31.

This also indicates that the transceiver is configured incorrectly.

What is the driver version that you are using?  It should emitted with
the rest of the detection information.

These messages should be reporting 21143-tyle timeouts.  What driver
version?  Have you tried a current driver?
