Package: linux-image-2.6.15-1-686
Version: 2.6.15-8
Severity: normal

Hello,

I can't use the power off button of my laptop to start the power off
sequence. I recompiled a vanilla kernel linux-2.6.15.6 (from kernel.org)
and the button works (without changing anything in user space) so the
bug seems to be Debian specific.

The button kernel module is loaded and the files are created in
/proc/acpi
$ find /proc/acpi/button/
/proc/acpi/button/
/proc/acpi/button/lid
/proc/acpi/button/lid/LID
/proc/acpi/button/lid/LID/state
/proc/acpi/button/lid/LID/info
/proc/acpi/button/sleep
/proc/acpi/button/power
/proc/acpi/button/power/PWBN
/proc/acpi/button/power/PWBN/info
/proc/acpi/button/power/PWRF
/proc/acpi/button/power/PWRF/info

but pressing the button has no effect.

$ cat /proc/acpi/button/power/PWBN/info
type:                    Power Button (CM)
$  cat /proc/acpi/button/power/PWRF/info
type:                    Power Button (FF)

I just tried with linux-image-2.6.14-2-686 (2.6.14-6bpo1 from
backports.org) and the power off button works. The button also worked
with previous official Debian kernels. I don't know exactly when it
stopped working.

I am using etch.

What can I do to help the debug?

Thanks

In fact it is my fault and the problem is now solved. I close the bug.

For the story:
- I wanted to be able to login as soon as possible. So I changed
  /etc/rc2.d/ to rename S99gdm in S14gdm
- the X server locked the /proc/acpi/event file
- then S20acpid starts and can't open /proc/acpi/event
- the ACPI events (like power off button) are not managed anymore

Sorry for the noise

PS: Debian should really do something to speed up the boot sequence.
