Upgrade from 6.12.65 to 10.13.66 hangs on boot

Recently updated a 6.12.65 system to 10.13.66.

On reboot after displaying the grub menu, it just hangs with a flashing cursor in the upper left corner.

Rebooting into the previous kernel works, but causes some other issues.

Any ideas on how to troubleshoot this?

This normally means the Kernel RPM didn’t install properly. Try ‘yum update’ again, when you boot back to the old kernel. If that doesn’t re-download the kernel, you should be able to run ‘yum reinstall kernel’, which will.

So in the old kernel, yum update didn’t do anything. I ran yum reinstall kernel, it downloaded the troublesome kernel again and installed it without error.

Still a flashing cursor after the grub boot selection. No error.

I have since removed the “quiet” and “rhgb” options from the kernel boot parameters to see if they were suppressing any errors. Still flashing cursor.
