Still happens (even more often than before) with

kernel 3.4.5
Mesa 8.0.99.git20120707
libdrm 2.4.99.git20120706
libllvm 3.1.99.svn20120708


The kernel logs now show much more of these lines:

[drm] nouveau 0000:00:0d.0: fail pre-validate sync
[drm] nouveau 0000:00:0d.0: validate vram_list
[drm] nouveau 0000:00:0d.0: validate: -16
[drm] nouveau 0000:00:0d.0: cal_space: -16
[drm] nouveau 0000:00:0d.0: cal_space: -16
[drm] nouveau 0000:00:0d.0: cal_space: -16
...


This bug is really easy to trigger, all you need to do is to enable KDE
standard desktop effects => lockup in less than 5 minutes !
