--- Comment #34 from Andreas Loew <awl1-hi6Y0CQ0nG0@public.gmane.org> ---
Bad news once again...

I applied the following single-line patch to a stock 3.12.4 kernel in order to
switch to the NV50 fence:

     if (ret) {
         NV_ERROR(drm, "failed to initialise sync subsystem, %d\n", ret);

but the result is that after the GUI login screen (gdm) which works fine, I get
a complete hang when GNOME starts up using compiz (cannot even switch to a text
vt any more) and lots of the following output:

(see the attached bz2 for the full log).

So does this mean that your proposal of switching to the nv50_fence won't work
for me?

In the meantime, I will continue and try kernel builds based on commits
"5e120f6e4b3f35b741c5445dfc755f50128c3c44^" and
"5e120f6e4b3f35b741c5445dfc755f50128c3c44" tomorrow...

Thanks & BR,
Andreas
