    You can't use a vector that is in the range assigned to I/O APIC
    interrupts (i.e. 0x31 - 0xee). Otherwise you'll get an overlap when the
    vector gets assigned to an ordinary IRQ line. Also you probably want a
    high-priority interrupt as the condition is serious, if not critical --
    system failures, such as bus exceptions, machine check faults, parity
    errors, power failures, etc. demand a high priority service.
