在经历了随机系统冻结之后，我认为问题已经缩小到 Wi-Fi 网络。每次我的机器启动并运行超过 24 小时后，它似乎都会崩溃，最后的日志条目表明它与网络有关。当我手动更改 Wi-Fi 网络时也会发生这种情况。冻结会停止一切 - 鼠标不动，外部驱动器停止加载数据，我无法ctrl+alt+f2或ctrl+alt+backspace重新订阅在系统上。主板是华硕 X99-PRO安装了最新的 BIOS 3301。

目前dmesg是空的。我还进行了内存检查，没有任何错误。我还重新安装了 16.04，并确保一切都是最新的。
我最近尝试关闭服务sudo service network-manager stop，然后系统运行正常。大约 30 分钟后，我再次打开它，它崩溃了，并报告了上述情况。
问题：除了获得 USB-WiFi 加密狗之外，还有什么想法为什么会发生这种情况吗？是我遗漏了什么吗，还是这是 X99-PRO 附带的板载 Wi-Fi 的一个错误？
答案1
几个月来我一直在努力解决死机问题。尝试了各种方法。其他内核。nvidea 的一些功能。安装 WICD 等等。
一天前，我在一篇文章中看到一条小评论：
删除 modemmanager
sudo apt remove modemmanager
这对我来说很有效。
我正在使用 MacBookPro 2012。
希望它也能帮助其他人。

我在使用 BIOS 版本 3502 的华硕 X99-E WS 主板时遇到了几乎相同的问题。崩溃与 kern.log 尾部描述的完全相同。我通过以下方式禁用 Networkmanager：
sudo systemctl stop NetworkManager.service
到目前为止一切正常（4 天）
