When you upgrade from CentOS 6.x to what?  7.x?  6.x to 6.x+1?

If you update the CentOS kernel package there is a slight risk that you
will mess up your grub.conf file and boot that kernel by accident.  The
easy solution is to exclude kernel-* in your yum configuration, so that
yum will never update the package.  (And FWIW I haven't seen this issue
in practice.)
