With that patch, it hangs like that:

I don't see anything after (XEN).
A quick debugging tells me that one processor is waiting at
smp_call_function and the other one has a bogus CR3, i.e. all four PDPT
entries are 0. I'll take a look later today if I have time.
I haven't yet reproduced this, but that may be because I've just found
that SMP boot for domain0 without CONFIG_HOTPLUG_CPU is broken (I end
up booting domain0 with a single processor, which isn't the behaviour
we used to have). I'll fix that regression first and then when I have
SMP domain0 hopefully I'll be able to repro the bug.
