Ubuntu 18.04.1 LTS Bluetooth-устройство [0cf3: 3004] исправлена ​​конкретная проблема в ядре, но не удается найти устройства

Я пытался включить Bluetooth на своем ноутбуке (Lenovo Ideapad-Y400), он идет с Bluetooth Atheros, у которого есть некоторые проблемы с ядром.

Во-первых, мне не удалось включить Bluetooth, но я понял, что запуск sudo rfkill блокирует bluetooth дважды, а затем снова запускается дважды sudo rfkill unblock bluetooth , меню конфигурации bluetooth смогло найти устройства и связать их, но через 1 минуту происходит сбой, затем bluetooth ничего не может найти. Кроме того, если я отключу bluetooth в этом конкретном случае, я не смогу включить его снова, мне придется снова запустить rfkill un / block , чтобы включить его.

Затем я попробовал решение из здесь , и оно сработало отлично, теперь я могу включать и выключать свой bluetooth. Похоже, эта проблема была в версии моего ядра, также я установил Ukuu, чтобы установить более новое ядро, но моя видеокарта вылетает (сейчас я использую исправленное ядро, чтобы заставить работать Bluetooth "Linux 4.15.0.39.48") . Но теперь мой bluetooth не может найти ни одного устройства. Я попытался запустить bluetoothctl , включил его ( включение ) и сделал его доступным для обнаружения ( обнаруживаемым на ), а также запустил ] сканирование на мой компьютер не может найти какое-либо устройство, на котором работает hcitool . То же самое с установкой bluez .

Вы можете мне помочь с этим, ребята?

Большое вам спасибо.

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