Do you also see these in 3.13-rc2 + http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?h=drm-nouveau-next&id=a7e4201f0f7d47e03b851f06f8987856e8d33083 ? If not, you can reorder the patches (git rebase -i) and bisect the rest. Basically the GPU is trying to write to some address that is either completely bogus or is stale, and its internal MMU won't let it. -ilia _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
