Good news.

I'm not sure, please try patch filed at http://bugzilla.kernel.org/show_bug.cgi?id=1141

Dear Yu,

Thanks, apparently this patch loops to reach S5 state. It seems to be a 
possible solution. Some questions:

1) The patch is against a 2.4 kernel. Can it be safely applied against 2.6?
2) How does the APM deamon switch-off the machine. Does it loops too?

Now, a third station (based on a Tyan board) has the same problem. This 
power-off problem is a real problem. It does not only occur under ASUS 
boards.

Maybe I miss something, but the main need of ACPI is to be able to switch-off 
a computer... Why is this patch not applied by default?

Best regards,
Jean-Michel

I heard that with powerdown trouble, can possibly be solved by using
userland deamons, like apmd for apm and acpid for acpi. I will try the
acpid for my laptop during the holidays.

Unfortunately, I believe ACPI and APM cannot be used at the same time.

I am quite sure that I misunderstand something in ACPI. Seriously, I cannot 
believe ACPI is not able to power-down computers. Can anyone explain me how 
to power-down a computer using ACPI? Is there a special script of something?

Think of servers running in rack-mounts. They need ACPI to cool down when 
there is no activity. How do you shut them down using ACPI?

Cheers, Jean-Michel

Sorry, I misread your message. The ACPI deamon loads the required ACPI 
modules. What alse can it do? IMHO, the problem does not lay here.

ACPI shutdowns well here on the same machine (L3800C), I don't recall having
any problems at all with any kernel, but it's possible I didn't test test7
extensively. Anyway, test11 shutdowns fine, so go upgrade your kernel to
fix that.

Thanks a lot. Maybe the reason for that is that I installed Kernel-2.6-test9 
from Debian unstable, and did not compile it myself. Can it be the reason?

Best regards, Jean-Michel

power-off problem : ASUS K7 + ASUS L3800 + Kernel 2.6-pre9

[Jean-Michel POURE]

Dear friends,

I recently installed Debian 2.6-pre9 kernel on two ASUS computers: a K7 
terminator and a L3800 laptop. Previously, I was using apm under kernel 2.4.

Under the nex kernel, ACPI seems to work fine as I can monitor various 
information. The problem is that both computers do not power-off.

When pressing the button, /etc/acpi/powerbtn.sh is executed and init 0 is 
trigerred.

if ps -Af | grep -q '[k]desktop' && test -f /usr/bin/dcop
then
    dcop --all-users ksmserver ksmserver logout 0 2 0 && exit 0
fi

/sbin/init 0

But the computers do not shut-down cleanly (no power-off). I checked their 
BIOS and in both cases, the latest versions are installed. /var/log/acpid 
shows normal information:

[Mon Dec 15 16:45:43 2003] received event "button/power PWRF 00000080 
00000001"
[Mon Dec 15 16:45:43 2003] executing action "/etc/acpi/powerbtn.sh"
[Mon Dec 15 16:45:43 2003] BEGIN HANDLER MESSAGES
[Mon Dec 15 16:45:44 2003] END HANDLER MESSAGES
[Mon Dec 15 16:45:44 2003] action exited with status 0
[Mon Dec 15 16:45:44 2003] completed event "button/power PWRF 00000080 
00000001"
[Mon Dec 15 16:45:46 2003] exiting

Do I miss something? This power-off question is quite a problem for me as 
everytime I start the computers, ext3 recovers files. Can anyone help me?

Best regards,
Jean-Michel
