Bug#649294: linux-2.6: Duplicate battery after suspend/resume

[Bertrand Marc <beberking@gmail.com>]

Package: linux-2.6
Severity: normal

Dear Maintainer,

After suspend/resume, the kernel seems to think I have 2 batteries, one empty and my real battery. Of course I have only one battery on this laptop (DELL Latitude E6400). It works fine after a reboot: acpi reports only one battery.

Here is the output of acpi -i -s before suspend:
Battery 0: Full, 100%
Battery 0: design capacity 5200 mAh, last full capacity 4464 mAh = 85%

Here is the output of acpi -i -s after suspend/resume:
Battery 0: slot empty
Battery 1: Full, 100%
Battery 1: design capacity 5200 mAh, last full capacity 4464 mAh = 85%

Do not hesitate to ask for more logs or output, I'll be happy to provide any information necessary.

Regards,
Bertrand
