Hi Alex.
Well, I read the bug report but still can't understand why in any
kernels < 2.6.26 I don't have any problems with battery reports and in
2.6.26 as soon as the message appears g-p-m starts to behave
incorrectly.

Anyway, I got back to 25.11 for now, if you have any other workarounds
for me to test please let me know.

Cheers,
Fabio
