Hi Jorgen,

                Here are the two kernel lines from your grub
configuration:

    kernel /vmlinuz-2.6.25.10-86.fc9.i686 ro root=/dev/dm-0 quiet
usbcore.au tosuspend=1 agp=off agppart=off
    kernel /vmlinuz-2.6.25.10-85.fc9.i686 ro
root=UUID=27915760-e016-4843-9d 85-6642e29dc74c quiet

I notice that the data passed with the root option is different in both
cases. I notice that the kernel line for the newer kernel points to a
device file, while your root option for the working kernel passes a
string of letters and numbers. *First of all*: Back up your
"/boot/grub/grub.conf" file.  Try copying the string of letters and
numbers from the working kernel line, and replace the device file name
with the letters and numbers. Good luck,

                        PS: You might try posting a bugzilla entry in
the Fedora Bugzilla system about this.

As I said in my post, I've tried with the UUID root line, still gets can't find /dev/root

You might try making a new initrd:  mkinitrd -o myinitrd ...

As far as I can tell, initrd seems to have some control over /dev/root.
