hi all, I have a problem with my CentOS 6.3 distribution only when I restart or turn off the machine it does not restart properly. remains in both cases black screen and then I do not understand exactly what he's doing. grub after I hit send and then darkness. only after that forcement for a further time the power cycle then it works. the kernel version is 2.6.32-279.14.1.el6.i686 where is the problem? thanks in advance cheers
