Only somebody who is aware of the problem could answer that. You might
want to do some trouble-shooting to figure out what has gone wrong.
You may examine the "kernel" package scriptlets: rpm -q --scripts kernel
You may run the commands found there in an attempt at reproducing the
problem. Some are shell scripts. However, since you've overwritten your
grub.cfg file already, it could be that the problem will not be reproducible
anymore. ;-)
