Now with power kernel 45 I don't have rebooting issue anymore when I close h-e-n (0.2-4) if the battery module is loaded (bq27x00_battery). Also I was able to mount for the first time 3.5" external hard disk and 16GB & 8GB USB sticks, that I wasn't able with previous kernel and h-e-n. For all of them I had to use x-terminal mounting.
