Since you have no flash in your system, disable the "mbvanilla" MTD 
mapping, and choose the generic uClinux one instead.  Deatailed 
instructions on this were posted in another reply to somebody else 
within the last week.

never seen this before.  Something's breaking your romfs image.

You can try mounting it locally on your dev machine, with the loop device:

$ mount -t romfs  -o loop images/romfs.img /mnt/tmp

or similar.  If it mounts and you can browse the filesystem OK, then it 
suggests it's being corrupted once it hits your board.

This might help narrow things down a little.
