NAK.
Zero means "no interrupt" in the Linux space. If you have a physical IRQ 0 remap it to a convenient number (eg map IRQ's + 1, or stick it on the end). The logical and physical IRQ numbering in Linux don't have to match up - and given some platforms have IRQ numbering per bus and the like clearly doesn't in many cases. - 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/
