acpi problems after upgrade vom linux-3.0.4-1-i686 to linux-3.0.6

After linux kernel upgrade from 3.0.4-1-i686 to 3.0.6-1-i686 acpi deamon is not working correctly. /proc/acpi exists but theres no battery directory so i cant access battery status. Its an samsung nc10 laptop. acpid is run teste wie "ps -elf | grep acpi". Downgrading kernel solved the issue. So i think it could be a problem with kernel config or module not beeing loaded.

Is someone having the same problem ?

Where can i get the config file use for kernel compilation for standard arch kernel ?

ACPI_PROCFS_POWER will be removed and has been disabled in linux 3.0.4-1 (http://mailman.archlinux.org/pipermail/ … 21696.html).

Hmm in 3.0.4-1 it is enable in 3.0.6-1 it is disabled. Gnomes battery applet ist still using it so i think i have to move to a custom kernel now(or rewrite the battery apple).

EDIT: sorry it not gnome battery applet the uses /proc/acpi/battery instead of /sys/class/power_supply/BAT1 it ist gnome-power-manager. Maybe there is a way to change this behavoir but havent found it yet.

EDIT2: i was wronge once more gnome-power-manager uses acpid to detect battery chage. acpid is obviously using /proc/acpi/battery.

I dont use gnome, but this sounds very odd. upower should be in charge of these sort of things, and acpid should not really have a functionality on a modern system... Could this be some fall-back mechanism? I also thought there was some acpid2 available now that does not use /proc?

I upgraded from 3.0.4-1 to 3.0.6-1 yesterday and I now get messages from xfce4-power-manager saying 'No kernel support'.

Seems there's more than one app using ACPI_PROCFS_POWER so it's disabling/removal was a bit premature.

== A bit premature, that. It seems instead to be caused by the upower upgrade to 0.9.14
