** Description changed: In all kernels since 2.6.39, the "irqfixup" and "irqpoll" options are no longer taking effect. I have several machines that need to boot with one of these options, and I see reports of this regression from multiple - other users.

The interrupts generate the same errors seen without these kernel options, e.g.: irq 19: nobody cared (try booting with the "irqpoll" option) - even though irqpoll, or irqfixup, is used. + even though irqpoll, or irqfixup, is used.
