That is very old kernel. Try removing new kernel, and then reinstalling 
it, and if that does not work try removing new kernel and installing one 
before that, then one before that. Something like "yum install 
kernel-2.6.32-279.22.1.el6.i686" should do it. List all kernels with 
"yum list kernel*"
