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;
