我在配备英特尔和 Nvidia 960m 的 Dell 7559 上运行 Ubuntu 16.04 时经常遇到系统完全冻结的情况。
我尝试在 grub 中添加之前解决方案中的一行，但没有成功。之前没有出现过问题，今天才出现这个问题。使用 Firefox 时出现此问题，使用 Chrome 时问题仍然存在。使用其他程序（如 WPS Office）时也会冻结。
这是最近一次冻结期间的一些最新 /var/log 信息。让系统重新运行的唯一方法似乎是强制重启。
当我写这篇文章时，它也意外重启了。
非常感谢您的帮助。
干杯

答案1
可能与此内核问题有关：https://bugzilla.kernel.org/show_bug.cgi?id=109051
该线程中的以下解决方案为我解决了这个问题： https://askubuntu.com/a/852080
通过编辑来禁用intel_cstates（省电状态旨在减少 CPU 废热和电量使用）/etc/default/grub：
sudo nano /etc/default/grub
查找包含GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
直接添加intel_idle.max_cstate=1在后面splash。
或者，如果您的 BIOS 支持这样做，请从那里禁用所述 C 状态。
注意：这是 不是 长期修复。禁用 C 状态会严重增加功耗和废热。只有在没有其他解决方案并且更新内核无法解决任何问题时才尝试此方法！

这可能是硬件问题。我猜你的硬盘有问题。你可以通过运行实时 Ubuntu 16.04 会话来验证。尝试在实时会话中重现该问题，如果你看到相同的冻结/滞后，那么这将证明我的假设是错误的，你应该能够通过重新安装来修复该问题。但如果你的实时会话运行顺利，那么很有可能是你的硬盘出现故障。我这么说是因为我在你的 /var/log 中看不到任何异常。
我朋友的笔记本电脑也曾出现过类似的问题，一开始他的操作系统死机了，几天后甚至无法启动。我通过实时 ubuntu 会话验证了硬盘故障，并决定更换硬盘。
