Well, I'm going to try following the rules, as I've just joined the list.  
I've looked quite hard for a solution to my problem, but perhaps I just 
haven't hit the right page yet.

I have an ACPI enabled 2.4.21 kernel, using acpi-20030619-2.4.21.diff.

I have chosen to compile in everything rather than use modules.

3) run dmesg to see if there are any ACPI related errors.

No errors; I see "ACPI: Subsystem revision 20030619" and some other useful 
stuff, but no actual errors.

Everything seems fine.

Right.  Here goes.  I'm not sure if my problem is actually ACPI-related.  I 
recently updated my kernel to the standard 2.4.21, because the SuSE-supplied 
kernel (2.4.18) for SuSE 7.2 was causing occasional hangs.  Everything is 
fine, and the hanging has gone away, but one problem remains: now, my PC 
won't power off at shutdown.  I've tried halt -p (and poweroff) manually, 
and all that happens is that I get a sound which I think is my hard drive 
(IDE) parking, but then the system stays switched on.

I tried APM, which I was using before, and ACPI, and neither will power off 
the machine.  With ACPI, if I "echo 5 > /proc/acpi/sleep", then the machine 
does power off quite happily, so I think ACPI is working more than well 
enough to enter the S5 state.  So what I'm wondering is if there's something 
in halt/init that I need to update to take into account the fact that I'm 
using ACPI.

The machine powers off quite happily under Windows.  Currently, I have 
"ACPI-aware OS" selected in the BIOS.

I'm using a Gigabyte K7S5A motherboard with the latest available AMI BIOS, 
and I've tried using a custom DSDT table with any compilation problems 
fixed, but I'm guessing, as the echo > sleep works, that the core of ACPI is 
working okay.

Any ideas, folks?  Even if no one can solve my problem, I'd appreciate a 
pointer to a good page which describes how the halt/poweroff commands 
interact with the kernel to perform a poweroff.

Thanks,

Matt
