CentOS - Jun 2010 - Error: when updating the latestt kernel 2.6.34 in centos 5.5

Hi,
I encounter a error when installing the latest kernel 2.6.34 in centos.
Steps:
1. download source code.
2.tar -xvf 2.6.34.tar.gz
3.use the .config file of current system in /boot directory.
4.make ,make modules_install, make install,
5.reboot.
6.error:: accur.
Reading all physical volumes. This may take a while ...
Activating logical volumes
  Volume group "VolGroup00" not found
Creating root device.
Mounting root filesystem.
mount: could not find filesystem"/dev/root"
setting up other filesystems.
...
After comparing the latest initrd.img and the current system initrd.img .
The differnce below:

the currenet system has more modules before excuting the LVM operations.
these modules is dm-mem-cache.ko ,  dm-message.ko  and dm-raid45.ko which
depends the others. I know the centos 5.5 ' s kernel is 2.6.18. which has
dm-raid45.ko module.
I do not know which  changes to 2.6.34 about LVM. I think the errro is about
the LVM.
Anyone can give me answer or advice. Thanks.

Hi,
You can check your .config file and CentOS config file.
(/boot/config-2.6.18-194.3.1.el5)
Many options must be =Y in the file.
and Re-building kernel is much taking your time.

Shortly, rebuild centos5.5 without LVM(root=/dev/hda) is a answer your question.

What is your purpose to try to run a recent vanilla kernel?

That should be "make oldconfig", shouldn't it?
