Kernel can't find root on lvm

	Hi Jorgen, 

		Here are the two kernel lines from your grub

>     kernel /vmlinuz- ro root=/dev/dm-0 quiet
> tosuspend=1 agp=off agppart=off

>     kernel /vmlinuz- 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,
