Switching back to the old kernel allows booting

Why does this happen??

This issue is quite common, but has multiple root causes—usually improper kernel installation, which can result in the following after booting:

  1. Some critical services fail to start because their drivers aren’t loaded.
  2. Or system-critical directories (/usr, /var, /opt) aren’t mounted during startup, causing essential services to fail.

From the first two screenshots, the system has successfully entered multi-user mode, indicating that the system has booted successfully. It’s likely that some services didn’t start properly. It’s recommended to log into the system, check the logs, identify the root cause, and apply the appropriate fix.

Reinstalling the graphics card driver and disabling SELinux can resolve the issue.
