Take a peek at what is inside the initramfs file:
~ $ mkdir initramfs
~ $ cd initramfs/
~/initramfs $ gzip -d < /boot/initramfs-2.6.32-220.el6.x86_64.img | cpio -id
73012 blocks
~/initramfs $ ls
bin cmdline dev dracut-004-256.el6 emergency etc init initqueue
initqueue-finished initqueue-settled initqueue-timeout lib lib64
mount pre-pivot pre-trigger pre-udev proc sbin sys sysroot tmp
usr var
~/initramfs $ find lib/modules -name '*.ko'
<snip>
If a module that is required to mount your system (ext3/4, dm_dm-raid,
etc - very system dependent) isn't in there, then the system won't be
able to boot. Sometimes they don't get added automatically, for whatever
reason. If you're able to identify the missing driver, edit this file:
/etc/dracut.conf
And add a line like this:
add_drivers+="name-of-driver"
Then re-run dracut. If you don't know how to do that, then you probably
should just rpm -e that kernel package, then re-install it.
Hope this helps.
