Public bug reported:
if i watch the nic LEDs while booting they go dark several times, which
i presume to correlate with hardware resets. after each reset, the LEDs
stay out for several seconds, longer than most nics. after the final
reset the LEDs don't come back on until after the system comes ready for
login. the network is functional on approximately 70% of bootups, but
is not functional on approximately 30% of bootups. from these
observations i'm guessing some stage of initialization of the e1000e
driver is sometimes missed or perhaps not waiting long enough before
giving up. is it effective to file such a bug here or ought i be
interacting with kernel.org?
