Greetingz!

"unable to mount root fs on unknown-block"
Means you need to compile-in (or build an initrd) support for your hard drive controller (or whatever your trying to boot your kernel on).

Here is how to update the initrd on Ubuntu:

Code:

sudo update-initramfs -u -v -k `uname -r`

Hope this helps.
