Public bug reported:
Applies to both qemu and qemu-kvm 1.0, but only when kernel is 64bit and
userspace is 32bit, on x86. Did not happen with previous released
versions, such as 0.15. Not all guests triggers this issue - so far,
only (32bit) windows 7 guest shows it, but does that quite reliable:
first boot of an old guest with new qemu (or qemu-kvm), windows finds a
new CPU and suggests rebooting - hit "Reboot" and in a few seconds it
will be locked up (including the monitor), with 100% CPU usage.
Killable with -9.
