我的笔记本电脑运行 Windows 10 和 Ubuntu 18.04 双启动设置已经有一段时间了（超过一年），没有任何问题。然而，今天早些时候，由于电池电量不足，我将笔记本电脑暂停到 RAM。然后，几个小时后，我尝试启动它，但它只会显示操作系统徽标（Kubuntu）几秒钟，然后关闭。
当它尝试启动时，我点击ESC查看内核的输出，发现以下输出（我只包含了显示某种故障的行）：

显然，似乎出于某种原因，我的 CPU 过热并导致 Ubuntu 崩溃和关机。但我能够毫无问题地启动 Windows 10，当我访问启动菜单时，CPU 处于健康的约 50 摄氏度。是我的内核出了问题导致它错误地测量 CPU 温度，还是在我尝试启动 Ubuntu 时出现了严重问题？这与挂起到 RAM 有关吗？我以前用过，没有问题。
我应该怎么办？
