ttm might call the move notify with null new mem placement, properly handle this case inside nouveau move notify callback.
This has been fixed already in a -next tree I sent to Dave.
I just tried -next with your patch (and two other fixes that I had sent):
drm/ttm/dma: Only call set_pages_array_wb when the page is not in WB pool drm/ttm/dma: Fix accounting error when calling ttm_mem_global_free_page and don't try to free freed pages
and Jerome's AGP fix: ttm: fix agp since ttm tt rework
and got the crash (but only with NVidia cards) after swapping between Xorg and the VCs. Look in drm-next.jpg

With your patch removed ("drm/nouveau/ttm: fix crash as a result of a recent ttm change") and the patch below by Jerome I still get it to crash (see drm-next-with-Jerome-fix-revert-Ben.jpg)..

Anything special to trigger it ? I can't trigger it with simple gnome3 session (firefox evince ...)
Cheers, Jerome
