我刚刚在我的华硕（7.7 GiB 内存、英特尔处理器 5Y10 CPU @0.80Ghzx4、英特尔高清显卡 5300（broadwell Gt2）、64 位、117.5 GB）上安装了 ubuntu 16.04 LTS。
sudo使用 5-15 分钟后，wifi 会关闭，但终端中的任何命令也无法使用。重启后，它通常会再次工作，但有时需要重启 2 次，我才能再次享受 ubuntu 5-15 分钟。
一开始我以为这只是一个 wifi 问题，但似乎与失去管理权限更相关？
已经排除故障两天了，甚至重新安装了一次。
有任何想法吗？

答案1
解决了。
仔细查看了/var/log/syslog（感谢 mikewhatever）并发现内核可能不是最合适的（--end trace---错误）。
从 4.10 版本切换到 4.4 版本现在运行正常，这解决了上述所有问题。
