Install an old kernel

Issue : My laptop has been acting up since my latest kernel update (at least that is what I am hoping it is).  I had run a clean-up on my machine to remove the older kernels.  I would like to re-install the most recent kernel. Resolution : [root@neo ~]# yum list --showduplicates | grep kernel.x86_64 | tail -2 | head -1 | awk '{ print "kernel-"$2 }' | xargs yum install [root@neo ~]# grep 2.6.32-279.1.1.el6 /boot/grub/grub.conf  title Red Hat Enterprise Linux Workstation (2.6.32-279.1.1.el6.x86_64) kernel /vmlinuz-2.6.32-279.1.1.el6.x86_64 ro root=/dev/mapper/vg_neo-lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_NO_MD quiet SYSFONT=latarcyrheb-sun16 rhgb crashkernel=auto rd_LVM_LV=vg_neo/lv_swap  KEYBOARDTYPE=pc KEYTABLE=us rd_LVM_LV=vg_neo/lv_root rd_NO_DM irqpoll initrd /initramfs-2.6.32-279.1.1.el6.x86_64.img Alternate ending: [root@neo ~]# yum list --showduplicates | grep kernel.x86_64 | tail -2 Unable to read consumer identity kernel.x86_...

EFI / UEFI RHEL 6.2 x86_64

Solution :  create a /boot/EFI partition type EFI (vfat) around 200m, along with your /boot type ext4 Issue : I had seen quite a bit of rumblings regarding EFI and Linux.  I was actually hesitant to even attempt the install because the experience sounded horrific. I had read somewhere recently that they were going to allow booting from an LVM-based /boot.  That should be good.
