Title:
  hpsa driver has problems with interacting with tape drives and media
  changer

Status in linux package in Ubuntu:
  New

Bug description:
  There are multiple problems with tape drives when using a media changer on an hpsa controller.
  The problem appears for example when you label tapes in Dell Netvault.

  The problem does not appear in current vanilla kernel 4.2.3.

  After bisecting the problem the actually first good commit is: 
  3ce438df106826edde7ad724f3819716a3f0cf56 is the first bad commit
  commit 3ce438df106826edde7ad724f3819716a3f0cf56

      [SCSI] hpsa: allow SCSI mid layer to handle unit attention

      We were clobbering the SCSI status and setting
      cmd->result = DID_SOFT_ERROR << 16; to get a retry,
      but better to let the mid layer handle the unit
      attention.

  thanks to git bisecting rules:
  good = label errors = old kernel
  bad = no label errors = newer kernel

  Please consider backporting that fix to the 3.13 ubuntu kernel.
