I have a had this same error on my system when trying to upgrade to the
planet CCRMA planetedge kernels. I had come to believe the my problem
was related to my root partition being on a SATA disk, and the switch to
libata (2.6.5 works for me).

The error means that whatever is supplied to the kernel with the "root="
parameter is not a valid device. In my case, this was "root=LABEL=/",
but it could be "root=/dev/hda1" or something like that.

So what do you have, and what is the previous version of kernel that
does work for you?
