Did you remember to set dentry->d_fsdata to NULL? This has to be done in sysfs_remove_dir() sometime during the period when dentry->d_inode->i_sem is held. Right now the pointer to the kobject never gets erased. That Badness message is an indication that you are using a valid pointer to a kobject whose refcount is 0.
