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.
Thanks, Jörg
