Hi,<br>
<br>
The laptop mode hint to disable auto-suspend didn't help.<br>
Also have tried one of the recent version along with Debian
experimental's version 5.40. But with no visible progress.<br>
<br>
- pressing the Capslock key still freezes the bluetooth keyboard<br>
- after some time the hid devices stops working with kernel logs
below:<br>
- keyboard must be switch on two times in order to get working1<br>
