Re: Interesting debugging: Specific packets cause some Intel gigabit ethernet controllers to reset

    Hi,

    Yes I had that issue, it was a firmware problem...  and a timed one
too :(

    We had a customer with a few Raid5 of 3 drives, once 1 drive go bad
he had about 20m before another drive would.

    And they where bricked btw, you couldn't just upload the new firmware.

    Wasn't an happy weekend.
