The above command says it can't find this directory:
I think it has something to do with not having the linux-tools for this kernel.
Can't install linux tools for latest kernel.
E: Unable to locate package linux-tools-4.9.0-040900rc2-generic
Or maybe I installed it wrong with dpkg... Got the .deb files here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9-rc2/
