Доброго времени! После обновления ядра перестал работать встроенный Bluetooth.

Не понимаю последний warning и собственно что делать то? На предыдущем ядре всё Ок, тоесть почти, аудио иногда подлагивает, вот и приобрёл свисток USB тоже Realtek, так на нём всё нормально и на этом ядре и на предыдущем!

соответственно поднят только один интерфейс, который свисток usb.
Вот думал что когда нибудь встроенный bluetooth заработает после обновы, а получается он вовсе отвалился! И после того как воткнул свисток сервис сразу поднялся
