Are you building your own kernel? That doesn't look like the default Ubuntu kernel. I would suggest to upgrade your kernel to 3.2.55 (of course use an updated grsec patch as well). If that doesn't fix the issue, try vanilla 3.2.55 (no grsec). If the issue persists, report it upstream (either to lkml/netdev or grsec, depending whether the vanilla 3.2.55 has the issue or not). Regards, Lukas
