acpi doesn't work sometimes

I am using an acer notebook with suse 10.0.

ACPI seems to not work arbitrarily. Sometimes it work and is started during boot, sometimes not.

I often get the message by kpowersave, that it could not start because of not running acpi.

When trying to restart i get this message:

acpid: can't open /proc/acpi/event: Device or resource busy

What's the problem and why is it so arbitrary?

I considered that it might be, that X is started before acpi. So I've already tried to reset the order at media:/hda6/etc/init.d/rc .

But this doesn't work...

regards

Hi,

cc'ing Soeren.

Some other daemon process acquired the the event interface before powersaved could. Identify the process with

lsof |grep "/proc/acpi/event"

In rare cases its known that users encounter races between services for the ACPI event interface. Only acpid should access the kernel interface directly; other user space processes should use the socket of acpid to collect ACPI events.

Since you're using SL 10.0 I suspect you're packages are not up-to-date.

As a fortuneteller: You've installed mobile selection of SUSE 10.0, thus IAL (iald) is running which acquires the ACPI event interface as fallback. On a Acer notebook its safe to drop iald.
