Interrupt Controller failures

Explanation: The system has detected an error associated with the interrupt controller(s) on the system motherboard.

Diagnosis: This is most likely a motherboard problem, but it might be caused by a bad expansion card as well. If the interrupt controller number is supplied as part of the error message, that might help narrow down the interrupt request line where the problem was detected, if applicable, although IRQ controller #1 handles all of the IRQs, some directly and others indirectly via controller #2. IRQ controller #2 handles IRQs 8 through 15.
