I tried deploying a trivial patch removing the check and saw no other problems. Is this a problem you have heard about?

I don't understand the drm code well enough to dive in deep on my own.It's a paranoia patch and any bo should not be created with NOUVEAU_GEM_TILE_NONCONTIG flag. Even if it happens to work it will fail on any sufficiently fragmented vram. What driver versions do you use? ~Maarten
I'm just using vanilla 3.12 kernel. Been using the nouveau driver for a long time, no problems until this printout due to the contiguous check.
