Any chance you could separate those two changes and isolatethe one which
causes the problem?

The docs for acpi=ht say:
        Using `acpi=ht` causes Xen to parse the ACPI tables enough to
        enumerate all CPUs, but will not use other ACPI features.  This is not
        common, and only has an effect if your system is blacklisted.

I doubt this is what you want for a reboot issue.

You should probably investigate the reboot= options instead.

Ian.
