SL6 kernel update - can't reach login screen

Since the latest kernel update to SL6, I am unable to login with the new kernel but have no problem with the previous one.
I am chainloading the SL6 boot loader from grub2. The new kernel is shown in menu.lst and grub.cfg of SL6.
This new kernel seems to be loading as the boot progress bar completes, but then that's it - doesn't move on to the login screen.
Should I reinstall the kernel packages that were updated ? I really have no idea as the previous kernel is problem free. Last thing I expected from rhel based OS.

Edit: Kernel stops loading after "Starting atd OK"

 

I know what the problem is. I think atd is followed by nvidia module which according to the Xorg.0 (old) log could not be loaded.

Code:

(II) LoadModule: "nvidia"
(II) Loading /usr/lib64/xorg/modules/drivers/nvidia_drv.so
(II) Module nvidia: vendor="NVIDIA Corporation"
 compiled for 4.0.2, module version = 1.0.0
 Module class: X.Org Video Driver
(EE) NVIDIA: Failed to load the NVIDIA kernel module. Please check your
(EE) NVIDIA:     system's kernel log for additional error messages.
(II) UnloadModule: "nvidia"
(II) Unloading /usr/lib64/xorg/modules/drivers/nvidia_drv.so
(EE) Failed to load module "nvidia" (module-specific error, 0)
(EE) No drivers available.

When I installed SL6, I blacklisted nouveau and installed nvidia 260,19.36 linux display driver togther with the corresponding -kmdl (from atrpms)

I also have dkms installed (rpmforge) and am disappointed that I should now have this problem.
What please is the best way to fix it and to prevent same from happening everytime a new kernel comes my way ?

(Have posted this also on SL6 forum).

 

Did you try to recompile the nvidia module?
Or reinstall the update?

Whew, all sorted. All I had to do was read the how to section in the SL6 forums.

Code:

yum --enablerepo=elrepo install kmod-nvidia

(Removed the packages originally installed from atrpms first of course).

 

So what third-party repos are you using now?
Mrk

 

At the moment I have the following enabled.. the puias is only for abiword - have added
includepkgs = abiword* to repo file.

 

sometimes also SELinux gives trouble during booting process i face that in early fedora's what i do is disable and then enable on permissive mode then again renable on enforce mode that help me manytimes
