x86 machines with more than 1 CPU will not power off automatically
under Linux AFAIK, because the halt code is not SMP-safe. (Er, why does
it need to be? You have to be in runlevel 0 for halt to work, all
filesystems umounted or mounted read-only, all processes kill -TERMed,
etcetera. IANAKernelHacker though.) Does your machine have more
than 1 CPU?
Quote:> I do not use modules
??! It's a bad idea to do that in most cases. What do you hope to gain
from not using modules? Adding a new device can be as simple as
"modprobe FOO", bouncing/resetting a troublesome device can be as simple
as "rmmod FOO && modprobe FOO", but without modules, you've gotta
recompile and/or reboot. Also, some things (PPP compression, LoseModem
support, 3D support for some graphics cards, support for all manner of
semi-esoteric hardware) are *only* available as modules.

Many x86 machines have a setting in the BIOS where you choose how the
machine responds to a power-button press. Usual choices are "suspend",
"off", "off after 4 seconds". Make sure this is set to what you want.

Hard to say. The Poweredge systems I've had experience with are left on
24/7, and only powered off when there's a problem requiring
