ACPI problems with 2.5.44 and IBM ThinkPad 390E

[David Härdeman]

Hi,

upon trying the latest devel kernel I got periodic messages from ACPI on my IBM ThinkPad 390E (and when I tried ACPI on 2.4.X it seemed to show similar problems). The messages are added below, other than periodic warnings, the /proc/acpi/battery/BAT1/info and status files show faulty charge levels and charge state as unknown. No real showstoppers though.

Regards,
David
