Kernel Switch Failure During Kdump Testing Using oec-hardware

What Can I Do If the Kernel Cannot Be Switched During Kdump Testing Using oec-hardware?

If the oec-hardware tool fails to execute the kdump test suite, manually reboot the system and check whether the kernel switching screen is displayed. If the screen is not displayed, run the dnf update command to update the system. After that, reboot the system and check whether the kernel switching screen is displayed. If the screen is displayed, test kdump again.
