Thanks. Just installed "linux-image-4.0.0-040000rc1-generic_4.0.0-040000rc1.201502261652_amd64.deb" - should I have installed somenthing else also? There was no "linux-image-extra" available this time.
Now - after installing and restart - the Bluetooth disappeared alltogether. It doesn't appear in menu bar anymore and if I go through Settings -> Bluetooth everthing is greyed out.
