[Xen-devel] (XEN) APIC error on CPU0: 04(40)
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 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

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''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; -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
