Basically, Auke wants you to throw away your NIC and/or motherboard. Since you're effectively dead, the only damage you can do by disabling the check has already been done. This unfortunately seems to be fairly common with e100, especially for the on-motherboard version, and you basically have two options: either disable the check or write an offline tool to reprogram the EEPROM. The latest netdev tree (if it's not in Linus' tree already, which it might be) does add back the option to ignore the check so you can update the EEPROM, which will automatically fix the checksum. -hpa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
