rfkill shows there is an hci0 device:
$ rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
But bluetoothctl does not detect any controller:
$ sudo bluetoothctl
08:58 Agent registered
08:58 [bluetooth]# list
[...no output...]
If you revert to the 4.4 kernel [4.4.0-1106.111 (76)] it works:
$ sudo bluetoothctl
