The new grub for some reason changed the naming scheme, I think they changed (hd0,0) to (hd0,msdos1) and so on.
I believe this is the naming convention since Grub2. The cause of this panic is usually the filesystem type not being identified by the kernel - I used to get it all the time in Slackware when I would forget to build an initrd with ext4 support after a kernel upgrade. In this case, maybe chrooting and then rebuilding the images using mkinitcpio should do the trick?
For the record, my own root partition is ext4, and is booting fine with the stock 3.2.11 kernel in the repositories.
