lvm, device-mapper, kernel errors! HELP!

2 weeks ago I updated the kernel with yum to 2.6.16-1.2115 by running yum update, and choosing only the kernel to update out of all the other updates available for my fc4 machine.
I rebooted the machine a couple of days ago and now receive errors as follows:

Computer loads modules #names of modules listed here
Making device-mapper control node
scanning logical volumes
reading all physical volumes - this may take awhile
no volume groups found #!!!!!!!!!
activating logical volumes
unable to find volume group "VolGroup00"
Error: /bin/lvm exited abnormally with value 5! (pid 586)
creating root device
#then it goes further into other errors like
error dup2'ing yada yada
kernel panic - not syncing

It's obvious to me that the kernel errors are brought on by lvm or device-mapper errors.
I'm running FC4 on a IBM server 206m with HostRAID, but I am not using raid since I was unable to install the drivers at setup. so I am just runnning off of one hard drive, however RAID is still enabled.

I tried disabling RAID support to see if it will boot into the kernel but it doesn't.

I can however boot into older kernels (2111) and use my server, but that's it.

Once I booted into the older kernel, I decided that since I updated only the kernel and didn't update other software like lvm2 and device-mapper that maybe this caused a problem, so I tried to update again and this time update to the newest kernel (2141) and update lvm2 and device-mapper. This however didn't fix anything.

Any suggestions! Really stuck here!
thanks
