[Firmware Bug] TSC_DEADLINE disabled due to Errata; please update microcode to [version](https://so.csdn.net/so/search?q=version&spm=1001.2101.3001.7020): 0x22 (or later)
BusyBox v1.27.2 ([Ubuntu](https://so.csdn.net/so/search?q=Debian&spm=1001.2101.3001.7020) 1:1.27.2-2) built-in shell (ash)
Enter 'help' for a list of built-in commands.

如果像我这样子是 /dev/mapper/ubuntu--vg-** 的错误,用 fsck 来处理
如我的这个情况就输入fsck -y /dev/mapper/ubuntu--vg-ubuntu--lv
输入后执行执行完毕后输入exit
就可以进入系统了。
