Device enumeration at boot doesn't detect acpi battery.

Hello,

Apologies in
advance if I sent this to the wrong place. I'm not sure where the kernel's boot-time device enumeration code lives. If this is the wrong forum, could someone please tell me the email address I should forward it to? Thanks.

I have a laptop running Linux 2.6.32-22-generic
#33-Ubuntu SMP x86_64. My laptop is an ACER Aspire 6930. When I boot, the battery isn't enumerated into "sysfs" like gnome-power-manager expects it to.

After boot, the following command finds nothing:
% find /sys -name "BAT1" -print

If I inspect the contents of one
of the files in the /proc/acpi/battery/BAT1 directory, they'll appear:
% cat /proc/acpi/battery/BAT1/state

present:                 yes
capacity state:          ok
charging state:          charged
present rate:            0 mA
remaining 
capacity:      3619 mAh
present voltage:         12131 mV

%
find /sys -name "BAT1" -print /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0A:00/power_supply/BAT1 /sys/class/power_supply/BAT1

This is repeatable on every boot. Once I "cat /proc/acpi/battery/BAT1/state", gnome-power-manager recognizes my battery (via upowerd) and all is well.

This is the
non-"gnome-power-manager" part of https://bugzilla.gnome.org/show_bug.cgi?id=617529

Can someone point me at the right forum, the code that needs to be modified, or better yet, fix the problem? I've never touched with the kernel code before.

All help is appreciated.

Hi, Brian,

please attach the acpidump output of your laptop. please attach the dmesg output after boot.
It would be great if you can file a new bug report at
https://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
and attach these info there.

thanks,
rui
