Anyone who is seeing this, please try adding the following line to the
end of function smp_error_interrupt() in xen/arch/x86/apic.c:
   show_registers(regs);

This will get a backtrace and let us see what code path is causing this
APIC error.

If we can start to narrow down the cause I can provide more tracing
and debug code to add as necessary.

I just started getting this error off of last nights build also.

Hi,

I get this error message.

(XEN) APIC error on CPU0: 04(40)

I found a spanish website, that says something about it, but I can't speak 
spanish.
http://www.guiadohardware.net/comunidade/faq-linux/189865/

As far as I can understand, they recommend the noapic option, or recompile the 
kernel with smo, or upgrade the Bios.

Is this a serious error?

Johnny
