System couldnt mount your rootfs and thats why it gives you kernel panic.
You should check your grub.conf and it should be something like

default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title RedHat Enterprise Linux ES 3
        root (hd0,0)
        kernel /vmlinuz-2.4.21-32.EL ro root=/dev/Volume00/LogVol00
        initrd /initrd-2.4.21-32.EL.img
title RedHat Enterprise Linux ES 4
        root (hd0,4)
        kernel /vmlinuz-2.6.9-11.EL ro root=/dev/VolGroup00/LogVol00 rhgb quiet
        initrd (hd0,4)/initrd-2.6.9-11.EL.img
title Fedora Core 4
        root (hd0,8)
        kernel /vmlinuz-2.6.12-1.1390_FC4 ro root=/dev/VolGroup02/LogVol00              
 	initrd (hd0,8)/initrd-2.6.12-1.1390_FC4.img
title Fedora Core 4 - Embedded
        root (hd0,6)
        kernel /vmlinuz-2.6.11-1.1369_FC4 ro root=/dev/VolGroup01/LogVol00
        initrd (hd0,6)/initrd-2.6.11-1.1369_FC4.img

Also be carefull while your are deciding hd0,0 issue cause when you get fdisk /dev/hda or /dev/sda
you gonna see something like

   Device Boot    Start       End    Blocks   Id  System
/dev/hda1   *         1        10     80293+  83  Linux
/dev/hda2            11       265   2048287+  8e  Linux LVM
/dev/hda3           266       330    522112+  82  Linux swap
/dev/hda4           331      4870  36467550    5  Extended
/dev/hda5           331       340     80293+  83  Linux
/dev/hda6           341       850   4096543+  8e  Linux LVM
/dev/hda7           851       860     80293+  83  Linux
/dev/hda8           861      1115   2048256   8e  Linux LVM
/dev/hda9          1116      1125     80293+  83  Linux
/dev/hda10         1126      1890   6144831   8e  Linux LVM

hd0,8 means hda(your harddisk) and partition 9 because 0,0 is your boot partition on hda 
On the other hand you should be carefull if you use LVM, VolGroup ID's and LogVol ID's are important. 
In my grub.conf I collect whole kernel images in my hd0,0 partition and just ES 3.0 has a boot loader.
