16.04.1を実行しているXPS 13 9360でBluetoothが機能しない

Intel 8265デュアルバンドワイヤレスカードを搭載したUbuntu 16.04.1を実行しているXPS13 9360があります。

カードは最初は認識されませんでしたが、linux-generic-hwe-Edgeパッケージをインストールした後、WiFiは問題なく動作し始めましたが、残念ながら、Bluetoothを動作させることができませんでした。

システム設定-> Bluetoothに移動すると、Bluetoothスイッチはオフに設定されますが、オンに設定しても何も変わりません。

$ lspci -nn
3a:00.0 Network controller [0280]: Intel Corporation Device [8086:24fd] (rev 78)

$ rfkill list all
    0: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
    1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

$ uname -r
4.8.0-34-generic

助けてくれませんか？
