# **Linux Ubuntu开机遇见的 [Firmware Bug] initramfs 问题**

[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.

结果如下图：

 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。
