An easy is to use netconsole. You can make all of the kernel log output
got a different machine on your network.

Your lspci tells me it is on 16 and 17. You should see in /proc/interrupts
on that line something about pciback?

You mean IRQ 39.

Look on Google for 'Wiki PVOPS' and there is a section on how to connect a
serial console.
With the serial console we can send those commands to the hypervisor even if
your box
is hanged.

I wonder if we have your IRQs confused. Can you provide the full cat
/proc/interrupts
and as well the serial bootup of the console? Or just the 'xm dmesg' and
'dmesg' output
if you don't have the serial console hooked up yet.
