在經歷了隨機的系統凍結之後，我想我已經將範圍縮小到了 Wi-Fi 網路。每次我的機器啟動並運行超過 24 小時時，它似乎都會崩潰，並且最後的日誌條目表明它與網路有關。當我手動更改 Wi-Fi 網路時也會發生這種情況。凍結停止了一切 - 滑鼠不動，外部驅動器停止加載數據，而我不能ctrl+alt+f2，ctrl+alt+backspace或者瑞斯在系統上。主機板是一個華碩X99-PRO安裝了最新的 BIOS 3301。

目前dmesg為空。我還做了一次內存檢查，沒有任何錯誤就通過了。我還重新安裝了 16.04 並確保一切都是最新的。
我最近嘗試透過關閉服務sudo service network-manager stop，然後系統運作良好。大約 30 分鐘後，我再次打開它，它崩潰並顯示上述報告。
問題：除了獲得 USB-WiFi 加密狗之外，您知道為什麼會發生這種情況嗎？是否有我遺漏的東西，或者這是 X99-PRO 附帶的板載 Wi-Fi 的錯誤？
答案1
幾個月來我一直在與冰凍作鬥爭。嘗試不同的事情。其他內核。與英偉達有關的東西。安裝WICD等
然後一天前在一篇文章中看到一條小評論說：
刪除數據機管理器
sudo apt remove modemmanager
這對我有用。
我使用的是 MacBookPro 2012。
希望它也能幫助其他人。

答案2
我在使用 BIOS 版本 3502 的華碩 X99-E WS 主機板時遇到了幾乎相同的問題。我透過以下方式禁用 Networkmanager：
sudo systemctl stop NetworkManager.service
到目前為止它正在工作（4天）
