Unexpected IO-APIC on Gigabyte GA-7VTXH and kernel 2.4.20rc1

[Ruediger Otte <tierra.y.libertad@gmx.net>]

[-- Attachment #1: Type: TEXT/plain, Size: 271 bytes --]

Hi,

I'm using a Gigabyte GA-7VTXH Board with the Athlon XP Processor and
linux kernel 2.4.20rc1. I get this message during boot:

WARNING: unexpected IO-APIC, please mail
         to linux-smp@vger.kernel.org

So, here I am.

dmesg is attached.
