And acpi (on interrupt 9) gets an interrupt storm, and gets disabled. But if I somehow got usb using irq 9, all my problems might vanish... -Stian - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
