This is what I was afraid of: even though the code allows you to bypass the EEPROM checksum, the probe fails on a further check to see if the MAC address is valid.

Since something with this NIC specifically made the EEPROM return all 0xff's, the MAC address is automatically invalid, and thus probe fails.

I don't understand why you think there is something wrong with a
specific NIC?

that was completely not my point - I was merely trying to point out that the original problem causes a cascade of error events later on, and bypassing the eeprom check in this case didn't help you at all. Something is wrong in the driver, but I don't understand yet why it only affects one of the 3 nics in your system.

In 2.6.14.7, e100.ko fails to read the EEPROM on 0000:00:08.0 (eth0)
In 2.6.18.1, e100.ko fails to read the EEPROM on 0000:00:09.0 (eth1)

almost sounds like a bug got fixed and it introduced a regression. this wouldn't be the right time to pull out git-bisect would it? even loading 2.6.15, 2.6.16, 2.6.17 on it would give us some good information.


Cheers,

Auke
