我的安装一直都很好，直到几天前，一次更新导致事情出现问题。我以为是它安装了新内核，但切换回 4.10.0-28-generic 也导致了同样的问题。我在戴尔 Latitude E6410 上运行 16.04 LTS，8GB RAM 和 nvidia 3100m，使用开源驱动程序。

那是我的系统日志文件。在 23:11 和 23:24 左右，我看到了一些奇怪的东西。根据我的记录，系统在 23:27 挂起。挂起时，系统完全没有响应。键盘和鼠标无法工作，指示灯上没有硬盘活动。我还有另外 2 个日志文件
https://drive.google.com/drive/folders/11I2va9bygapm9N34G6W2QEi1HBzKXSk5?usp=sharing从底部滚动，您可以分辨出哪些是重启后的情况，哪些是冻结前的情况。安装 4.13.0-26-generic 后，情况变糟了。当时我使用的是 NVIDIA 驱动程序。但我不得不删除它们并恢复默认设置。

发现了一个有类似问题的帖子。https://bbs.archlinux.org/viewtopic.php?id=224938。有人认为问题可能出在虚拟盒模块上。

因此，我决定将执行时列出的模块列入黑名单，lsmod | grep vbox
方法是将它们输入到/etc/modprobe.d/黑名单-firewire.conf按照https://linux-audit.com/kernel-hardening-disable-and-blacklist-linux-modules/
不用说，我再也没有遇到过任何死机的情况。运行了几个小时，tail -f /var/log/syslog没有出现任何先前的错误。
Virtual Box 5.2.6 和 iwlwifi 驱动程序似乎存在问题。我认为这与内核 4.13.0-26-generic 关系不大，因为我在启动到以前的内核版本时也遇到了同样的问题。4.4 和 4.10
https://unix.stackexchange.com/questions/118116/linux-what-is-a-tainted-kernel是一篇有趣的文章，帮助我理解“Tainted”的含义。
