[elrepo] Hanging video input with Nvidia kmod-nvidia-295.71-1.el6.elrepo.x86_64

[Kenneth Halanych]

I recently upgraded from Scientific linux 6.1:
the NVidia driver
kmod-nvidia-290.10-1.el6.elrepo.x86_64
nvidia-x11-drv-290.10-1.el6.elrepo.x86_64
with kernel vmlinuz-2.6.32-131.21.1.el6.x86_64

to Scientific linux 6.3:
with NVidia driver
kmod-nvidia-295.71-1.el6.elrepo.x86_64
nvidia-x11-drv-295.71-1.el6.elrepo.x86_64
with vmlinuz-2.6.32-279.1.1.el6.x86_64.


When I login to my gui (GNOME gdm) it will hang and freeze. In /var/log/Xorg.0.log the following is recorded:

I know that Xorg-server was updated between SL6.1 to SL6.3.  The issue looks similar to the bug reported at (https://bugzilla.redhat.com/show_bug.cgi?id=618356). I have tried downgrading the NVidia drive and the using the old Scientific Linux kernel to no avail.

Any suggestions on how to correct this incompatibility (?) would be most appreciated.
