It doesn't work on a few systems. It seems to be an issue with some
ACPI implementations.
For example, I have the same problem on my T61 running amd64
GENERIC.MP... which is really annoying on a laptop without working
suspend. I once even forgot to push the power button after shutting
it down and it keept running in my laptop bag until the battery ran
out...
It seems to depend on the cpu too. After I switched my Sempron to a dual
core Athlon64 neither i386 nor amd64 were powering off. The i386
platform attempted to powerdown (the fans and drives spinned down) but
before the computer was powered off the machine rebooted. Both platforms
worked with the single core. Then in october or november last year some
change in the acpi code made the i386 powerdown again, but no such luck
on the amd64.
I guess that I have an interessting acpi table in the bios, acpidump
will die with a segmentation fault while decoding the tables. But I got
no time to look into that yet.
Kind regards,
Markus
