An unexpected IO-APIC was found

[Michael Ben-Gershon <mybg@netvision.net.il>]

I received the following message from the kernel:

An unexpected IO-APIC was found. If this kernel release is less than
three months old please report this to linux-smp@vger.kernel.org

I am not quite sure what I am meant to report. I am using an ASUS
P4S800 board. kernel 2.4.24 (standard).

The stuff I think is relevant from dmesg is as follows:

If there is anything else I can help with, please let me know.
