In principle ACPI shouldn't be needed, but in its absence the BIOS must provide an MP table and the x86-64 kernel must still have code to parse it -- otherwise I/O APIC mode won't work. I don't know if that's the case or not. I suggest you boot normally (with ACPI fully enabled) and send a bug report to LKML and the ACPI list with the interrupt routing info from the kernel log. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
