Battery state "freezes" after this.. So if it was charged to 90%, it will
be 90% forever. Also information about charger (plugged/unplugged) is not
updating... BIOS automatically increases display brightness just after
plugging charger but powersave thinks that it's unplugged.
After turning laptop off I can't turn it on any more.. I can hear fan noise,
but it don't boots (There are no even BIOS splash/message)
I should remove battery and wait ~5 seconds...
v2.6.26 was non-working here, but as far as I remember, there was no such
problem with 2.6.25. It's very difficult to reproduce it (this is just
second case for ~2-3 weeks). So bisecting is impossible.
Any ideas? Should I fill a bugreport?
