An unexpected IO-APIC was found

Hi,

although my kernel release is more than three months old, I dare to send this 
report, since it might nevertheless be of some value. I do not understand 
what it is about, though, but I do know a little about APIC. 

If it is not too much, please let me know, if this mail is of some value and 
-- if this is still not too much -- give me some explanation, or a link.

Thanks

Andreas Schenk

I have SuSE linux 9.0, with kernel
