WARNING: unexpected IO-APIC on 2.4.19-pre4-ac3

I'm getting the following with 2.4.19-pre4-ac3 on boot and in dmesg. Was also getting the message on stock 2.4.18 as well. The message told me to mail the list so I'm just following instructions :-).

        testing the IO APIC.......................

        IO APIC #1......
        .... register #00: 01008000
        .......    : physical APIC id: 01
         WARNING: unexpected IO-APIC, please mail
                  to [email protected]
        .... register #01: 00178020
        .......     : max redirection entries: 0017
        .......     : PRQ implemented: 1
        .......     : IO APIC version: 0020
        .... register #02: 00000000
        .......     : arbitration: 00

I know the message is coming from /linux/arch/i386/kernel/io_apic.c

        printk(KERN_DEBUG ".......    : physical APIC id: %02X\n",
reg_00.ID);
        if (reg_00.__reserved_1 || reg_00.__reserved_2)
                UNEXPECTED_IO_APIC();

reg_00.__reserved_1 is from struct IO_APIC_reg_00 defined in /include/asm-i386/io_apic.h

Any ideas what the apic would return to cause this is coming up? I'm using an i860 chipset with a dual Xeon.

Thanks,

Troy
