We've seen machines that won't reboot for a variety of reasons in the
past. In some cases this has seemed to be due to hardware being in a
state that the BIOS didn't expect. Hitting the SMI trap behind the ACPI
register might work around this, but I suspect that in many cases we
could achieve the same effect by spending more time trying to work out
whether there's any common themes in the failures.
