Summary: Current kernel config presents 2 batteries to the system
when only 1 exist
Product: openSUSE 11.0
Version: unspecified
Platform: Other
OS/Version: Other
Status: NEW
Severity: Normal
Priority: P5 - None
Component: Kernel
AssignedTo: kernel-maintainers@xxxxxxxxxxxxxxxxxxxxxx
ReportedBy: mboman@xxxxxxxxxx

Found By: ---


I'm using kernel 2.6.24-rc2-git4-2-default on a ThinkPad T43P.
The current kernel config, presents 2 batteries to the system even though I
only have one.

(See also Bug#497442 in GNOME Bugzilla).

This is the ouput from lshal;

The kernel is reporting two battery devices, one from /proc/acpi/battery/X (old
interface) and one from /sys/class/power_supply (new interface):
