Very odd. All stores in that commit are to ->d_parent->d_inode->i_dir_seq of in-lookup dentries. And if ->d_parent in those gets buggered, we were really deep in trouble. Could you try to reproduce that without __d_move() or __d_add() parts and see which one ends up triggering that crap? Note that we don't *use* ->i_dir_seq yet...
