Hi again! In the last days, I did a bit of further testing on my problem. It now seems that my first diagnosis was not entirely correct. I observed that the error occurs when I exchanged the battery while the system was running. If it is suspended to disk after that, it produces the error mentioned before on resume. If the battery is exchanged while the machine is powered off or suspended, there is no acpi error. Perhaps this behavior yields some clues as to what could be wrong?
