F15 Upgrade kernel won't run.

[linux guy]

My computer will not boot the F15 kernel after doing a preupgrade.   Nothing
happens when the boot process usually starts running.  Not a single line of
startup is displayed on the screen.

This happens both if I run preupgrade or preupgrade-cli.

Everything seems to go fine during the preupgrade process.   All the files
download and run fine, no errors or anything.

Other kernels on the computer boot fine.

Its like it can't find one of the boot files.

Any ideas ?

Thanks !
