I think it was already covered with this basic question :
<<<
Are you using the latest code?
      Make sure you use the latest available Nouveau code from the git
repositories listed in FrontPage: DDX, DRM and Nouveau kernel. And
this really means GIT, not your just distribution's latest package.
GIT as of TODAY . Kernel.org git repositories do not count, use the
freedesktop.org repositories. As long as Nouveau is in staging in the
Linux kernel, the user space ABI can break. This means that the git
version of libdrm or DDX does not work with the kernel.org version of
Nouveau code, until the changes flow upstream.

But I added a new section anyway.
