Kernel Panic - Not syncing : VFS: unable to mount root fs on unknown-block (0,0)

After updating more than ~1000 things my installation of RHEL 2.6.32-220.el6.x86_64. I get the following kernel panic message: > Kernel Panic - Not syncing : VFS: unable to mount root fs on unknown-block (0,0) I am able to boot with the bootloader by selecting the previous version. I've tried: dracut -f initramfs-2.6.32-754.23.1.el6.x86_64.img 2.6.32-754.23.1.el6.x86_64 and: dracut --regenerate-all also my grub.conf file was missing initrd below the new (1st) kernel: initrd /initramfs-2.6.32-754.23.1.el6.x86_64.img So I added it. I still get the kernel panic afterwards. I've tried to yum update on the old kernel and it will not update complaining about:

Since I updated the system originally, will the old kernel still need the 1000 updates? In other words are the files that were updated the same files that the old kernel uses when booting?
