So, we can see that the old stack also sees the phantom device, tries to identify it and fails. But I guess that that happens rather quickly (?) an= d, certainly, there are no endless retries. That seems to be the main differe= nce between the old code and the new one. I would try to draw attention of CAM experts like Scott Long or Alexander M= otin or Kenneth Merry to this bug. I'll re-assign this bug to scsi@ as well.
