Hello,

	Emailing this because of the message via syslog.  

Heres the output:

 Intel made a bug in this APIC.  That's a known issue and is bering worked
on.  Thanks for your report.

register #02 seems to be the bad register, it has bits "00178020" where
something more like "02000000" would be more appropriate.

It seems that these boards have the interrupts going to CPU0, hmmmm any
one know whats going on with these boards?
