Could be that you have problems with your initrd-image. Have you created it?
Also check that you have all the filesystem related things in kernel you 
need like lvm, ext3, etc. compiled correctly. As the error sounds like 
it can't find either the initrd-image and/or root filesystem.

If nothing else helps you could download the Fedora kernel source 
package and fix it so that it uses the kernel patches of ChronOS (Will 
probably need quite much tinkering).

In any case you should ask the people maintaining that ChronOS that 
which distribution they use and use that. It will save you with lot of 
headaches in future. These scientific projects can be really picky on 
which platform they run in addition to kernel version.

PS. Don't top post. It's quite rude to do so in this list.
