Прерывает и зависает с rtl8723ae

Question

Используя xubuntu 17.04, мой ноутбук случайно замерзает без видимых причин. Это может произойти сразу после загрузки или через некоторое время. Вся ОС зависает, и она не реагирует на ввод с клавиатуры или мыши, и единственным решением будет принудительное перезапуск.

Я знаю, что боль в a * устраняет эти непоправимые проблемы, но Я понятия не имею, как это сделать.

Моя единственная подсказка, прямо сейчас, кажется, указывает на карту Wi-Fi. Пару раз после перезагрузки от замораживания ноутбук все еще не реагировал, а top показал, что ksoftirqd использует 100% моего процессора, а в /proc/interrups там, где более 60 миллионов прерываний от PCI-MSI-1048576-edge rtl_pci, которые я собираю , имеет отношение к Wi-Fi.

Раньше у меня были некоторые проблемы с этой картой. Иногда, мой wifi моего ноутбука упадет случайно. Интернет внезапно перестанет работать (только для моего ноутбука), и после отключения Wi-Fi, чтобы попытаться снова подключиться, он просто не будет подключать или даже обнаруживать точки доступа. После установки этих драйверов проблема, похоже, исчезла.

Надеемся, полезная информация:
