Ubuntu 20.04 冻结并崩溃

我最近使用软件更新从版本 18 LTS 升级到 20，从那时起我注意到系统随机冻结或崩溃。

\n

症状\n崩溃通常始于某些窗口完全冻结（无响应）（与代码或 Firefox 相比），并且在短时间内（30 到 60 秒）整个系统冻结，唯一的方法是通过电源按钮重新启动。\最近，我还注意到一些即时崩溃，整个屏幕变黑。\n我还注意到，崩溃通常发生在使用 Firefox 或 VS Code 时（但不是在有意执行硬计算时）。

\n

/var/崩溃

\n

最新的文件是 3 天前的，最后一次崩溃是在今天。

更新 #4 - 解决方案？\n按照@heynnema的建议，我更新了BIOS。（令人烦恼的是宏碁只为 Windows 提供更新，所以这很有趣）。我也添加intel_idle.max_cstate=1了/etc/default/grub，现在崩溃已经停止了。
\n
更改的提示grub位于错误代码中 bug soft lockup CPU#2 stuck for 23 s，仅在崩溃时显示一次。（通常屏幕只是黑屏而不显示日志）。
\n

正如@heynnema所建议的，我更新了 BIOS。 根据许多其他网站的建议，我编辑 /etc/default/grub并添加了

intel_idle.max_cstate=1 processor.max_cstate=1

在GRUB_CMDLINE_LINUX=""

NVIDIA 硬件也会发生类似的崩溃；这里解释一下。

仅仅更新 BIOS 并不能阻止崩溃，尽管这种情况发生的频率较低。我不明白，为什么改变会grub停止崩溃。
