On 11.10 a few minutes after reboot on this notebook the battery symbol in the panel turns to no battery available, normal values in the sys interface turn to 'No such device' messages and 'voltage_now' gives a wrong number.
Here is a recent thread

and 'BAT1/current_now' gives 'No such device' on post #7
