acpi poweroff

acpi poweroff

[André Pereira de Almeida]

When I try to poweroff my computer, it reboots.
The only way to turn it off is to change

acpi_sleep_prepare(ACPI_STATE_S5);

to

acpi_sleep_prepare(ACPI_STATE_S4);

in the function acpi_power_off in the file drivers/acpi/sleep/poweroff.c.
I think it's a buggy acpi controller.
What's the side effect of this change?

This is a clue to track down to the root.
What's your machine model and kernel version?
Thanks,
Luming

It is a AMD Athlon XP 1700+ processor with a Asus A7S266 Motherboard. If 
it is of any help, the header of de ACPI's FADT says:
OEMID: ASUS 
OEM Table ID: A7S266VM
OEM Revision: 1.0B
Creator ID:  MSFT
Creator Revision: 1011

Sory, I forgot the kernel version: 2.6.12-rc3-mm3, but It's also happens 
in 2.6.11.8, 2.6.12-rc3 and 2.6.12-rc4
