It means that the initramfs files of the new kernels are not loading
dmraid either because the dmraid module is not being loaded, "dmraid
-ay is not being run or both."

Do you have any dracut and/or dmraid errors in
/var/log/messages
or
/var/log/boot.log

Is there a dmraid directory or module in
/usr/share/dracut/modules.d
