Subject: /proc/acpi/ac_adapter/AC is missing after latest ACPI merge

Hi all,

After latest ACPI merge /proc/acpi/ac_adapter/AC has gone fishing :

[~]> ls -al /proc/acpi/ac_adapter/
dr-xr-xr-x 2 root root 0 Şub 12 20:44 ADP1

[~]> ls -al /proc/acpi/ac_adapter/ADP1
-r--r--r-- 1 root root 0 Şub 12 20:44 state

This at least breaks HAL which thinks AC is always plugged in, is this change
intentional?

Regards,
ismail

lsmod |grep ac

Could you please clarify what is incorrect - ADP1 name ...? Why does HAL think so?

Thanks.
Vladimir.

[~/GIT/linux-2.6]> grep CONFIG_ACPI_AC .config
CONFIG_ACPI_AC=y

[~/GIT/linux-2.6]> lsmod|grep ac
af_packet 19976 2
cpufreq_userspace 3732 0

But it looks like older kernels had only /proc/acpi/ac_adapter/ADP1 and it
worked fine with HAL, maybe something in sysfs changed? Also for some reason
hal-addon-acpi doesn't seem to start at all, which might be the problem.

It was indeed a sysfs problem which commit
c2b6705b75d9c7aff98a4602a32230639e10891c fixed.
