Also the whole things seems somewhat un-deterministic. This morning I booted and the the Login screen nothing works. No keyboard input, touchpad won't move the cursor. Powerbutton works and will power off the machine. Then, u-boot starts and it stopped with some inputs, like it seems those keys I entered at the login scree, which shouldn't be at all NEVER....a few reboots and then it works normal. Very strange...
