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.
