If as I assume I cloned right repo
$ git clone -b drm-misc-next
git://anongit.freedesktop.org/drm/drm-misc linux-drm-misc-next
for my hardware last commit on this branch is turned out completely unworking.
Instead of the GDM login screen I see a black screen and hear howls of GPU fans.

In the kernel logs I see general protection fault:
