But the netwoking code sould survive this. <12 billion more page allocation failures> Are you using jumbo frames or have you manually set the MTU to something enormous? Because 32k is a pretty crazy amount of memory for the driver to be trying to allocate - it's going to fail all over the place, as you have discovered. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
