This problem should be fixed now, we debugged it for a long time. E.g. https://bugs.freedesktop.org/show_bug.cgi?id=23847 The commit: http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?id=7798546495c04a810db86be34ba1f39e370fd325 "drm/nouveau: fix missized allocation for ttm_bo_global struct" I hope that solves your issue. -- Pekka Paalanen http://www.iki.fi/pq/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
