The oops is characteristic of the underlying device being removed from visibility before the class device, and sure enough we do device_del() before transport_unregister() in the scsi_target_reap() routines. I've no idea why this is suddenly showing up, since the code has been in there since that function was first invented. However, I've confirmed this fixes Andrew Vasquez's boot oops.

P.S. I told you if you waited a while I'd get another bug ...
