Just in case it helps, I can tell you what the stack traces for those
"Badness" lines indicated.
The first one ('class_obj') was from scsi_remove_host() ->
scsi_forget_host() -> scsi_remove_device() -> class_device_unregister()
...
The second one ('iosched') was from scsi_remove_host() ->
scsi_forget_host() -> scsi_remove_device() -> device_del() ->
bus_remove_device() -> device_release_driver() -> sr_remove() ->
del_gendisk() ...
(That sr_remove() would be sd_remove() for you.)
The third one ('queue') was from pretty much the same path as the second.
