I=E2=80=99ve noticed that there have been reports of problems with Intel = X520-SR2 network interfaces stopping working. I think I=E2=80=99m seeing = a similar issue where the 10Gb interfaces stop receiving traffic = (they=E2=80=99re being used in promiscuous mode to sniff traffic from a = tap). ifconfig shows the interfaces are still active and the links are = OK. ifconfig down/up restores activity. I=E2=80=99ve changed = hw.intr_storm_threshold=3D8000 but I couldn=E2=80=99t tell if the = interrupt storm threshold had been triggered at the time the interfaces = stopped passing traffic.
