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 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
