我最近升级到了 Ubuntu 22.04，我的戴尔笔记本电脑开始意外关机。好像我的 CPU 突然达到 100%，然后就关机了。
在很多情况下，我无法完成最简单的任务，例如打开 VS Code，在其他情况下，它会在我登录几秒钟后关闭。有时我会看到一条错误消息，说它由于温度原因而关闭，但机器摸起来总是很凉。
这在 Ubuntu 20.04 上从未发生过。
笔记本电脑规格：
- 戴尔公司 Inspiron 15 3510
- 16 GB 内存
- CPU：英特尔®奔腾(R)银牌N5030 CPU @ 1.10GHz × 4
- 显卡：Mesa Intel® UHD 显卡 605 (GLK 3)
- 磁盘：512 GB
- 大概3个月大。
以下是一些有用的日志：

尝试在早期阶段加载 coretemp 模块：
printf "# BUGFIX: pre load coretemp to fix Laptop Thermal Shutdown Bug\ncoretemp\n" | sudo tee /etc/modules-load.d/bugfix-coretemp.conf
重新启动并查看问题是否已修复。
