Thats the issue, boot process tries to detect root filesystem, but it
can't. Some reasons for this I know are:
1. Storage controllers are not in kernel and initramfs
2. Pointing wront root device

I could say that both of the problem does not exist.
Now question why configuration worked on jaunty and why not in karmic??
