Re: Reversing Kernel Levels
I have a laptop that won't boot into any 3.x kernel I've tried. That means that I have to make sure that the old 2.x kernel from F14 doesn't get removed. I've learned that if I boot into that one kernel, I can do this as root:
yum remove kernel
and it will remove all installed kernels except for the running one. Try booting into the kernel you want kept and using yum to remove the rest, but don't use the -y option because you'll want to make sure yum is doing exactly what you want before confirming. (If it doesn't, you can always specify the kernel version on the yum command line.)

Any advice in this post is worth exactly what you paid for it.
