Hi!

ACPI is acting up on me.  On my main machine, ACPI used to be unable to
power the machine down.  It just said "Power down." and the said there.
It worked flawlessly with my notebook (Dell Inspiron 8k).

Now, since about 2.4.10 (?) the situation reversed.  Now ACPI can power
down my desktop just fine but my notebook just sits there after the "Power
Down." message.  Normally, I press the power button then, but yesterday
I was too busy and let the machine sit there and to my utter
astonishment, the notebook did power down after several minutes!  I
didn't take the exact time, but right now I'm sitting besides the
notebook which said "Power down." exactly 3 minutes ago and still is
powered on.  Any ideas?

Felix

Hi. My computer is:
- Athlon Barton 2600+
- Asus NFORCE2 chipset
- 512 Mb
- Kernel 2.4.27

Im trying to have ACPI. First i compiled battery, thermal, processor, 
etc.. in modules but when i do modprobe processor for example it show this:


/lib/modules/2.4.27/kernel/drivers/acpi/processor.o:

modprobe: insmod /lib/modules/2.4.27/kernel/drivers/acpi/processor.o failed
modprobe: insmod processor failed


If i compile the modules inside the kernel if i do cat 
/proc/acpi/processor/limit for example i have:

not supported

What is wrong?

More Info:

$ cat /proc/acpi/info
version:                 20040326
states:                  S0 S1 S4 S4Bios S5


$ cat /proc/acpi/sleep
S0 S1 S4 S4Bios S5
