Question Kernel Panic re Ext3?

I recompiled my Red Hat 8.0 kernel which started at 2.4.18-14 to bring it up to 2.4.21 (I got the tarball, etc.). Upon reboot up comes GRUB with my new choice, which is named 2.4.21-030813. On making that choice I end up seeing

EXT2-fs warning (device ide0(3,1)):ext 2_read_super: mounting ext3 filesystem as ext2
VFS: Mounted root (ext2 filesystem) read only.
Freeing unused kernel memory: 108 k freed
Warning: unable to open an initial console.
Kernel panic: no init found. Try passing init= option to kernel.

Ideally, you would give me an exact technical explanation of each of these lines, in complete English language sentences, and what I should do to get over the panic and arrive at the desktop. Short of that, just tell me what to do to get over the panic. Here is all the information I can think of providing that could be relevant. Obviously, I am a newbie, so if you need me to provide other information, please let me know.

The STANZAS OF /boot/grub/grub.conf are as follows:

title Red Hat Linux (2.4.21-030813)
root (hd0,0)
kernel /vmlinuz-2.4.21-030813 ro root=/dev/hda1
initrd /initrd-2.4.21-030813.img

title Red Hat Linux (2.4.18-14)
root (hd0,0)
kernel /vmlinuz-2.4.18-14 ro root=LABEL=/
initrd /initrd-2.4.18-14.img

Here are other pieces of information.

# cat /etc/fstab

My only desparation has to do with getting out of the Kafkaesque torture of trying to look things up about Linux on the world wide web. By the way, if you do have an authoritative reply to this query, please allow me to ask a follow up question or two. Thanks very much.

maybe you missed a step when you were recompiling, like make clean or something....take a look at this link and go through it and make sure you took all necessary steps..
