Comment 8 for bug 769092

Sorry Kristijan, I forgot to subscribe myself to this bug and so did not see your subsequent comments.

To install the mainline kernel download the two *amd64 and the *all.deb from http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ into a a new folder, e.g. /home/your_home_name/mainline. See to it that the are the only deb files in that folder. In a terminal then type:
sudo dpkg -i --recursive /home/your_home_name/mainline
