Your system was most likely rebuilding the initrd, and you interrupted it leaving you with a broken initrd. Try booting off a rescue disk and chroot into the install, and run: dracut -f -v to regenerate all the initrds. Also, you don't need to reinstall the kernel but just do a 'yum update' to get everything up to the latest release. The shim package with the fix is the latest. -- Jonathan Billings <billings at negate.org>
