You can try with newer kernels from ElRepo (http://elrepo.org/tiki/tiki-index.php) that have compatible API's with EL6. look for elrepo-kernel section on main page. Currently there are kernels 3.0.83-1 and 3.9.7-1. But do note that those are third party kernels, even though ElRepo is safe third party repository. -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe StarOS, Mikrotik and CentOS/RHEL/Linux consultant
