More data points:
I can boot Xen with SMP, and a dom0 kernel with 'nosmp' and it works.
I can then start a domU kernel with 'nosmp' on cpu1 and it works, but
if I try to start an SMP-enabled domU kernel, it dies with the same error.
I have been playing with kernel config options, so far to no avail. I
tried to enable cpu hotplug support, but the final kernel link fails due
to a missing symbol.
