[SOLVED] Unable to access resume device

[callkalpa]

I get the following message when I try to boot and I can't boot.

Unable to access resume device UUID=a6c5a4e5-0802-4109-8ff1-c1ac097be069
mount: could not find filesystem /dev/root

Here is my /boot/grub/menu.lst

Here is my /etc/fstab

And here is the output of 'rpm -q kernel'

kernel-2.6.27.21-170.2.56.fc10.i686

How can I solve this problem, hope that the above info will help.

Something is wrong with UUID only. Quick fix is, replace UUID with actual device name assigned to partition ( /dev/sdx ) in menu.lst and /etc/fstab files.

I did but it didn't solve the problem

[devils casper]

Post the output of fdisk -l command here. Post the edited files too.

I solved the prob.
I removed the current kernel and removed the fedora-updates repo.
Installed kernel and it installed kernel 2.6.27.5-117.fc10
Edited the /boot/grub/menu.lst accordingly and it booted absolutly with no errors.

Seems the error is with grabby. After installing the kernel it said "grubby fatal error"

Thanks for you all for helping and let's hunt for this "grubby error"
