--- Comment #6 from Alexandre Courbot <gnurou at gmail.com> ---
I have tried reverting the following patches as suggested on
http://lists.freedesktop.org/archives/dri-devel/2014-November/072367.html:

809e9447: "drm/nouveau: use shared fences for readable objects"
055dffdf: "drm/nouveau: bump driver patchlevel to 1.2.1"
e3be4c23: "drm/nouveau: specify if interruptible wait is desired in
nouveau_fence_sync"
15a996bb: "drm/nouveau: assign fence_chan->name correctly"

Doing so helped with another (unrelated) issue I was having, but sadly did not
change anything to this problem or its symptoms. Looks like we are dealing with
something completely different, even though somehow fence-related.

Also FWIW, running weston-simple-egl with the -b option (eglSwapInterval 0)
leads to the same behavior as glmark2.

I will keep investigating where/why the fences are blocking.
