Comment 14 for bug 1311192

Jean Marc, now that we have those mainline results, as per https://wiki.ubuntu.com/Kernel/KernelBisection one would want to execute a terminal:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git linux
cd linux
git bisect start
git bisect good v3.12.18
git bisect bad v3.13-rc1

this will give a commit which to build a kernel from following the previously mentioned article.
