Solution to failure to boot after Ubuntu kernel upgrade: ubuntu Kernel

Ubuntu has always reminded me to upgrade the kernel. I can't help it today. Then GG goes, and an error is reported directly at startup.

[Firmware Bug] TSC_DEADLINE disabled due to Errata; please update microcode to version: 0xb2 (or later) ...... a lot

It seems that the CPU microcode is not the latest version, which causes problems.

Solution

To quickly restore my previous system.

Restart your computer
After the instance is started, choose grub> advanced options> previous kernel version> Enter,

Enter System
Delete the latest kernel
Open the command line Ctrl + Alt + T

// View the currently used kernel # uname-a // view all the kernels of the current system # sudo dpkg -- get-selections | grep linux-image // Delete the just-updated kernel # sudo apt-get autoremove linux-image-4.13.0-36-generic // restart the system # sudo reboot

In this way, the kernel version is restored to the previous version, and will be updated after a more stable kernel version is released.
