Motorola S9 and BlueZ 4.14

Starting the bluetoothd daemon and pressing the headset power button I
get the following (the headset is paired but it does not make a
difference):

bluetoothd[21459]: link_key_request (sba=00:1D:60:69:91:18,

removing from list

Any ideas of possible causes of the "stream state change failed:
Input/output error"?
