Hello Laurence,
Did you run your tests with that patch applied? If so, it would help if
you could rerun your tests without that patch. If the above patch makes
a difference it means that it can happen that __scsi_remove_device()
does not change the device state into SDEV_DEL. That's a bug and we need
to know whether or not __scsi_remove_device() behaves correctly.
Thanks,
Bart.
