I now see the following additional problems: - System freeze on resume (occures always). - System freeze on shutdown (occures sometimes) - System freeze when BT-mouse is connecting (occures sometimes). Then I can't do anything except power off. This happens only if Bluetooth AND BT-mouse is activated.
