Now, after a new fresh install of centos and this kernel, the laptop boot properly and when the laptop hibernate after closing the screen the restart is fast and efficient. I also notice a very faster network with these new drivers! But I think I still have a problem with modules added by virtual box. If I install this application the problem come back as with previous kernel. Mays be hibernation it is not supported with virtualbox and the modules it adds...
