    Subject[PATCH 2.6.27-rc8 0/1] e1000e nvm fix
    Please apply to 2.6.27

    This is related to regression bugzilla:

    This patch is meant to prevent all future corruptions of the
    e1000e NVM (non volatile memory) after the driver is loaded. The
    registers stay locked until the machine is power cycled.

    This should allow us to move forward with debugging without
    allowing any other bad element or the e1000e driver, to write to
    the NVM area unexpectedly.

    Currently we (Intel Ethernet) are reproducing the issue on
    multiple machines in house, we are working on the issue with the
    other core Linux teams here at Intel and within the community. No
    resolution yet but we are much closer now.

    Later we will post patches to help users who have had this
    problem restore their eeprom from either a saved image from
    ethtool -e or from another identical system.

    There is a set of patches to help clean up the driver's use of
    the hardware/software semaphore, but those are un-necessary to be
    immediately applied once we're locking the NVM. We will push
    those for inclusion within the merge window for 2.6.28.
