    Added netdev to get more attention to this.

    What do you call 20-50% packet loss ?
    (Losses to icmp flood itself, or tcp losses ?
    Is the machine answering to icmp flood, or is it the origin ?

    Are you saying packet loss was not occurring with 2.6.30 ?

    Could you describe your methodology ?

    You could give us results of "cat /proc/interrupts" from both
    versions, because it sounds as an interrupt affinity problem.

    # cat /proc/interrupts
    # tc -s -d qdisc
    # ifconfig -a
