Thanks for the mail!
/usr/src/kernel folder is fine and it got all related folders.
Followed the following steps:
1) Burned 4 Image disks and 4 source disks
2) Using image disks upgraded to RHEL4 Update3 from RHEL4 base
3) Copied "kernel-2.6.9-34.EL.src.rpm" from "source disk4"
4) rpmbuild –-rebuild –target i686 kernel-2.6.9-34.EL.src.rpm
5) Copied the kernel source "linux-2.6.9.tar.bz2" from "/usr/src/redhar/SOURCES/" to "/usr/src/redhat/BUILD/kernel/"
6) Extracted linux-2.6.9.tar.bz2 (this is created as a result of Step 4)
7) make menuconfig (enabled application related options along with the existing ones)
8) make clean
9) make bzImage
10) make modules
11) make modules_install
12) make install
Checked the following things:
1) "vmlinuz" and "initrdXX.img" got created successfully under "/boot"
2) Image is visible in "/etc/grub.conf"
Please suggest if I have to follow any more steps to get rid of this problem.
Thanks & Regards,
Sailaja

Did you check kernel folder under /usr/src?
i think you miss some steps.
In these links you will find how to Building the Kernel

you probably didn't make an initrd or forgot to compile in a key
component you need...
"make install" in the kernel source tree is a good way to make sure
there is a valid initrd...
