Problem Description:
If I compile the kernel with ACPI support then when I try to shutdown computer,
it wrote "acpi_power_off called" and reboot instead of power down.
with APM all works fine. 

Steps to reproduce: halt, poweroff, shutdown -p now

Comment 1 SGh 2004-09-02 22:58:03 UTC

It seems like I find a solution, byt I can't implement it...
in file drivers/acpi/sleep/poweroff.c
I add line

#include </usr/src/linux/arch/i386/kernel/apm.c>

and in function acpi_power_off I comment all lines and replace it with 

apm_power_off

Now when I try to power off, it wrote 

acpi_power_off_called
GENERAL PROTECTION FAILURE (or something like).... (and many lines)

I think that for use APM to power off I must uninit ACPI first and init APM,
When I try to add 

apm_init
apm_pwer_off

to acpi_power_off function then it says That "32bit BIOS access not supported" (or something like) and PROTECTION FAILURE again
Anybody know how can I do it???

Could you please check if the problem still exists in a recent kernel (2.6.9)?
If it does, could you please attach dmesg output and /proc/acpi/dsdt and
/proc/acpi/fadt?

Thank you, guys!!! In 2.6.9 Seems like it work fine, it power off my computer properly! THANKS! :)
