type of errors. Common to all of them is the line
last sysfs file:
/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:00/PNP0C09:00/PNP0C0A:00/power_supply/BAT0/energy_full
and it does not happen without smapi patched into the kernel.
Please request additional information if needed.
It's a plain vanilla kernel version 2.6.32.7 on amd64, with tp_smapi patch
version 0.40 directly built into the kernel.
Sincerely,
Daniel
