Hi,
 
   I have installed Fedora Core 5 with kernel version 2.6.15.
Now i have updated and compiled the kernel version 2.6.16-13 with more debug statements.
 
When i rebooted the system after compilation its not able to boot. Its giving kernel panic :
 
   Kernel Panic not syncing : VFS :Unable to mount root fs on unknow-block(0,0)
 
The grub file is :
 
       default=0
       timeout=10
       splashimage=(hd0,0)/grub/splash.xpm.gz
       hiddenmenu
       title Fedora Core (2.6.16-Kernel-2.6.16.13.EL.PTY)
          root (hd0,0)
        kernel /vmlinuz-2.6.16-Kernel-2.6.16.13.EL.PTY ro root=LABEL=/1 rhgb quiet
        initrd /initrd-2.6.16-Kernel-2.6.16.13.EL.PTY.img
        title Fedora Core (2.6.16-prep)
        root (hd0,0)
        kernel /vmlinuz-2.6.16-prep ro root=LABEL=/1 rhgb quiet
        initrd /initrd-2.6.16-prep.img
        title Fedora Core (2.6.15-1.2054_FC5)
        root (hd0,0)
        kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=LABEL=/1 rhgb quiet
        initrd /initrd-2.6.15-1.2054_FC5.img
 
Upon changing the grub file to :
 
        title Fedora Core (2.6.16-Kernel-2.6.16.13.EL.PTY)
          root (hd0,0)
        kernel /vmlinuz-2.6.16-Kernel-2.6.16.13.EL.PTY rhgb quiet
        initrd /initrd-2.6.16-Kernel-2.6.16.13.EL.PTY.img
 
 
Its continously rebooting without loading kernel .
 
 
Can anyone one help me on this?
 
Thanks & Regards,
