So, I had someone else report this today... I'm not sure how or why this
hasn't showed up more... It is a WITNESS panic which is already fixed in
the later patch. If you edit /usr/src/sys/dev/drm/nouveau_mem.c and
search for the line containing drm_sg_alloc(). Place the DRM_UNLOCK();
and DRM_LOCK(); around that call it should get things going. See below.
