LinuxQuestions.org - Kernel Panic while booting with a newly compiled kernel

Hi

I am a newbie to kernel programming.
I am now stuck with a problem and require your help.
What I did:

* Installed RHEL Server release 5 ( Tikanga ) kernel 2.6.18.8.el5 on an i686 machine.
* Downloaded 2.6.25.2 from kernel.org and unzipped it to a local folder.
* I did a make modules followed by make install
* Then I built the kernel using make bzImage.
* Copied the bzImage to /boot
* Did a mkinitrd with the 2.6.25.2 version and copied the .img file to /boot
* Edit grub.conf with a new title to boot bzImage and newly created initrd.

On booting I get the following error. Don’t know how to proceed from here.
Can someone help me. Please let me know if you require any more details.
Since I am new to this forum and Linux kernel programming I have no idea what data
Is relevant for this issue.
