Wi-Fi (Уничтожитель 1535) проблемы после обновления заголовка Linux 4.4.0-53

Я распознал некоторые "улучшения" своего соединения Wi-Fi на моем Dell XPS 13 9360 DE после последнего обновления заголовка Linux.

ОС: Ubuntu 16.04 LTS

Я беру спустя 3 минуты после начальной загрузки для соединения с моим Wi-Fi, и я не мог соединиться снова с Wi-Fi после того, как пробуждение от спит/приостанавливает.

Все работали, прежде чем я обновил заголовки ядрa Linux.

Я получил эту ошибку в dmesg:

Микропрограммная-5.bin проблема не релевантна, но я не получаю те другие errros прежде. Кто-либо получил те же проблемы или получил решение для этого?

Спасибо
