This is due to a lost APIC interrupt acknowledgement. A workaround is to boot with the `noapic' LILO option. This long-standing and very nasty problem was discussed extensively a week or two ago. Suspicions were cast at the disable_irq() function but I'm not sure anything 100% conclusive was arrived at. I guess I'll have to find a way to make disable_irq() go away, see if that helps. - - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
