rpm -Uvh elrepo-release-6-8.el6.elrepo.noarch.rpm
yum --enablerepo=elrepo-kernel install kernel-lt -y
yum --enablerepo=elrepo-kernel install kernel-ml -y

yum -y --enablerepo=elrepo-kernel install kernel-ml.x86_64 kernel-ml-devel.x86_64
yum --disablerepo="*" --enablerepo="elrepo-kernel" list available

uname -r
sed -i 's/^default=1/default=0/' /etc/grub.conf
reboot
