VFS: Cannot open root device "LABEL=/" or 00:00

[Evan Panagiotopoulos]

After updating my system I received the following error:

VFS: Cannot open root device "LABEL=/" or 00:00
Please append a correct "root=" host option
Kernel panic: VFS: Unable to mount root fs on 00:00

My grub.conf file is:
default=0
timeout=10
splashimage=(hd0,1)/grub/splash.xpm.gz
title Red Hat Enterprise Linux ES (2.4.21-32.EL)
        root (hd0,1)
        kernel /vmlinuz-2.4.21-32.EL ro root=LABEL=/ hdc=ide-scsi
        initrd /initrd-2.4.21-32.EL.img
title Red Hat Enterprise Linux ES (2.4.21-4.EL)
        root (hd0,1)
        kernel /vmlinuz-2.4.21-4.EL ro root=LABEL=/ hdc=ide-scsi
        initrd /initrd-2.4.21-4.EL.img

As you can see I have two kernels available. The "older" kernel ,
2.4.21-4.EL, is running just fine. Since the new kernel is more up to
date, I would much rather try to get the other on working.

I checked and compared the referenced the img files and here is the
info:
-rw-r--r--    1 root     root       165303 Apr 19 21:58
initrd-2.4.21-4.EL.img

-rw-rw-r--    1 root     root       164452 May 18 15:01
initrd-2.4.21-32.EL.img

and I see that both files are similar except that the new kernel has
an extra "w" in the group.

The other two files are the same:
-rw-r--r--    1 root     root      1236945 Oct  3  2003
vmlinuz-2.4.21-4.EL

-rw-r--r--    1 root     root      1252573 Apr 15 21:34
vmlinuz-2.4.21-32.EL

Any ideas?

Thanks,

Evan
