    Subjecte1000e: 2.6.27-rc1 corrupts EEPROM/NVM
    Hi,

    2.6.27-rc1 kernels appear to corrupt the EEPROM/NVM of the 8086:294c
    ethernet device (ICH9 I think). After hacking the driver to ignore the
    bad CRC and MAC address I could view the EEPROM with ethtool and it was
    all 0xff.

    Testing EEPROM reads and writes with ethtool appeared to work but after
    a reboot of the system the ethernet device (see lspci -v output) was no
    longer present. Could invalid EEPROM contents with a valid CRC (as
    would be the case after my read/write tests) result in the device
    failing to enumerate on the PCIe bus?

    David
