If there is any locking issue lockdep should warn about it. Lockdep will turn itself off after the first splat, so if the lockdep splat happens before running the affected parts those will have to be fixed first. ~Maarten _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
