Ubuntu 18.04.1 Bluetooth-устройство LTS [0cf3:3004] исправлена ​​конкретная проблема с ядром, но не удалось найти устройства

Я пытался включить мой Bluetooth моего ноутбука (Lenovo Ideapad-Y400), он поставляется с Bluetooth Atheros, у которого есть некоторые проблемы с ядром.

Прежде всего, я не смог включить Bluetooth, но понял, что sudo rfkill block bluetooth дважды, а затем снова запустите sudo rfkill unblock bluetoothМеню конфигурации Bluetooth смогло найти устройства и выполнить их сопряжение, но через 1 минуту оно перестало работать, и Bluetooth ничего не может найти. Кроме того, если я выключу блютуз в этом конкретном случае, я не смогу включить его снова, мне придется снова запустить rfkill un/block чтобы включить его.

Затем я попробовал решение отсюда, и оно работало как чудо, теперь я могу включать и выключать свой Bluetooth. Кажется, в версии моего ядра была эта проблема, также я установил Ukuu для установки более нового ядра, но моя видеокарта вылетает (сейчас я использую пропатченное ядро, чтобы заставить мой bluetooth работать "Linux 4.15.0.39.48"), Но сейчас мой блютуз не может найти ни одного устройства. Я пробовал бегать bluetoothctlи я включил его (power on) и сделать его доступным для обнаружения (discoverable on), а также работает scan on мой компьютер не может найти ни одного устройства, работающего так же hcitool, То же самое, установка bluez,

Можете ли вы помочь мне с этим, ребята?

Огромное спасибо.

Здесь я добавляю некоторые выводы, которые на некоторых форумах просят их получить контекст системы.
