    Thanks Akemi. 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
