Maybe I've misunderstand but if you have more than a single processor, I
thought you must not use ACPI. Otherwise it may think, oh one of the
processors is idle so I can power down... (and not realize your other
processor is busy)
However, this seems inconsistent with it not working when you then come
back up.
I guess we'd need to see your /var/log/syslog for more info...
