It's something to do with the gendisk. I'd have to look in block, but I believe the queue takes a ref to the gendisk. The scsi_device has a ref to the queue and the scsi_disk (in sd) has a ref to both the scsi_device and the gendisk. That means, until sd is unbound and the scsi_disk released, there's an implied unbreakable reference chain. at least, I think that's what the problem is.
