Sandy Bridge

Lots of newer mainboards have the Intel Sandy Bridge chipset. There is no out of the box support for it under 1004.

Add repos, install kernel backport and upgrade

The following steps help rectify the problem by utilizing some backport ppas (Shamelessly copied from http://www.subcritical.org/running_ubuntu_lts_on_sandy_bridge/)

apt-add-repository ppa:kernel-ppa/ppa
apt-add-repository ppa:glasen/intel-driver
# the next wasn't needed for my MSI Sandy Bridget board 
# apt-add-repository ppa:f-hackenberger/x220-intel-mesa 

apt-get update
apt-get install -y linux-image-generic-pae-lts-backport-natty
apt-get dist-upgrade -y

After doing that the backported kernel gets installed, as well as installed packages updated.

Fixing softlinks and access rights for MDs

Changing dcerouter's /tftpboot/<id of MD>/vmlinuz and initrd.img softlinks to the newly installed files, as well as chmod +r those newly installed files, the next boot of the MD resulted in a successful AV Wizard run, as well as VDR HD playback of MPEG4 encoded live TV.

Failing to change the symlinks will result in the MD still using the old kernel.

Failing to change the access rights will result in a read error upon PXE boot.
