"Kernel panic - not syncing:" problem after FC10 upgrade

I recently upgraded from FC7 to FC10 (Also, the Kernel from to
I did the upgrade through Yum (First installed the fc10 rpms, then did yum upgrade).
Now the new Kernel won't boot.

These are the options in GRUB for the new Kernel

kernel /boot/vmlinuz- ro root=LABEL=/ rhgb debug
initrd /boot/initrd-
It stops with this message

VFS: Cannot open root device "LABEL=/" or unknown block(0,0)
Please append a correct "root=" boot option. Here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I have verified that the device hd0 and its partitions are present (Pressing tab in Grub menu shows (hd0,0), (hd0,1) etc.)
I have changed root=LABEL=/ to root=/dev/hda1 (also tried hda2 and hda3) and still the same result!

Then I tried to boot my old kernel

These where the options..
kernel /boot/vmlinuxz= ro root=LABEL=/ rhgb debug
initrd /boot/vmlinuxz=
Then it hangs after some messages (shown below)

Waiting for driver intialization
Trying to resume from LABEL=SWAP-hda3
No suspend signature on swap, not resuming
Creating root device
Mounting root filesystem
kjournald starting
ext3-fs: mounted filesystem with ordered data node
Setting up other filesystems
Setting up new root fs
no fstab.sys, mounting internal defaults
Switching to new root and running init
unmounting old /dev
unmounting old /proc
unmounting old /sys
My machine is AMD 64 and I have two disks, one PATA and one SATA. The PATA disk
has four partitions and holds the OS.

Can someone please help? Did I blow something up during my upgrade?

That's one heck of an upgrade. I never do upgrades, only fresh installs but where I've seen people successfully upgrade from one version to next subsequent version work okay, I have never ever seen anyone go from that far back. I mean to begin with was the /etc/fstab file done the same way on F7 as is done currently???
