You didn't say what kind of CPU you have. Nor if you compiled
your kernel or if you used a distros' kernel.
One thing (just to eliminate this being a power management issue),
is to do this on the Linux command line:
xen-acpi-processor.off=1
It would also help if you provided the .config you are using. There
are some options you should not have one (like XEN_DEBUGFS.. something).
