Try to search google and the kernel mailinglist archives first. This
interrupt is generated by the Programmable Interrupt Controller. If you
disable it, you'll get rid of the message. AFAIK, this message only
shows up with VIA chipsets and is entirely harmless. You can avoid
having the message printed by setting the
print-kernel-messages-to-console level lower (man dmesg, man klogd).
