I took a quick look at arc.c and see that the trim_map_free() calls = don't take into account ashift. I don't know if that has anything to do = with your problem though. I would expect this would just make the trim = less efficient, but I need to dig further. -- Justin On Oct 16, 2013, at 4:42 PM, "Justin T.
