Please be aware that this is not a "fix" but rather is a "workaround."
 The problem is still there, the "acpi=off" just forces a different
set of code to do the turning off (apm).  Also, this workaround has
some pontentially undesirable consequences.  For instance, my laptop
uses acpi for processor frequency scaling and power management.  If I
turn it off, these won't work, which would be fairly bad.  If you have
a desktop, I'd say the chance that it needs acpi is much less.  I
guess you just have to weigh whether you need acpi and if you can deal
with manually powering off your system.
