    Subjectr8169 MAC problem
    From
    Looks like the r8169 MAC bug is still lurking:

    This obviously doesn't work very well. Full power-cycle back into
    2.6.26 fixes the problem:

    Based on googling around, I'm going to guess this might be related:

    Ivan Vecera (1): r8169: read MAC address from EEPROM on init (2nd attempt)

    Any ideas?
