Forgot some system specs:

- Q45 chipset
- Q9400 quad core processor
- 64bit dom0(debian lenny), started HVM with windows XP

Starting an PV domU with kernel 2.6.18.8-xen doesn't give these messages
and doesn't lockup the box.

> It keeps doing this, but at such a rate it is effectively rendering the box
