有人能向我解释一下我在 dmesg 中看到的这些错误消息吗？我是 Ubuntu 和 Linux 世界的新手。

答案1
CPU 过热并进入 MCE（机器检查事件）...即：它正在崩溃。如果您在系统日志中没有看到其他与温度相关的事件，则可能是因为您的 CPU 冷却器/风扇/热管/导热膏没有发挥作用。
使用此命令检查系统日志
terminal...grep -i -e temp -e therm /var/log/syslog*如果机器很脏/满是灰尘，这可能会导致机器过热。请清理干净。
如果您的机器有英特尔处理器，请确保已
intel-microcode安装。sudo apt-get update sudo apt-get install intel-microcode reboot安装
thermald以尝试控制温度。sudo apt-get update sudo apt-get install thermald reboot检查您的 BIOS 版本。开机时输入 BIOS，并记下版本号。访问制造商的网站，了解您的计算机品牌/型号。转到支持/下载部分，查看是否有更新的 BIOS。
最后，如果这是一台较旧的机器，则很有可能需要重新涂抹位于处理器和热管/风扇冷却器之间的导热化合物。这需要一些技术经验。
