That was the same symptom on mine when the root partition cannot be
mounted for some reason.

I had some luck on a broken Gutsy upgrade by adding "ide1=noprobe
ide2=noprobe" to the kernel line. However, with a clean install I had
no such problems. This makes me think that I may have been victim of a
problem with the initramfs after the upgrade. I suspect you may have
the same problem. I suggest you refine your google with this in mind to
get the solution as I don't remember it off the top of my head!
