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

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

[Hans-Christian Armingeon]

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?

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

What can I do to help tracking down this issue?

Is this a serious issue?

Thanks in advance,

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.

Building now, I will send the trace shortly

Thanks for that, very useful.

I'm guessing you have a uniprocessor P6 system?

I've checked in what I believe is the correct fix to the unstable
repository. The patch won't go public for a couple of hours, so you
can confirm I found the problem by adding the following lines after
the ASSERT line in on_selected_cpus() in xen/arch/x86/smp.c:
    if ( nr_cpus == 0 )
        return 0;

Ah well, I guess the AMD APICs behave like P6 APICs.

I am actually on a single proc sempron 64, but I have it
compiled and running as a P6 because I didn't feel that 64bit
support for everything that I run is entirely ready.
I will add that line, rebuild and let you know.

Thank you very much!

I've been a bit busy today. I have an Athlon64, which runs xen for amd64.
