Namely, both mp_parse_prt() and pcibios_fixup_irqs() do the IO_APIC_VECTOR() translation on irq, the result being IO_APIC_VECTOR(IO_APIC_VECTOR(irq)). I wonder if this is the cause of some bug reports with acpi and pci vector? Maybe mp_parse_prt() should not do the irq->vector translation? --Mika - 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/
