  Log Message:
  -----------
  When a CAM-managed device responds to a command with an error condition,
CAM may automatically retry the command following some error recovery
protocol.  For instance, it may send a SCSI START UNIT command to the
device before retrying the failed command.  In this case, an in-memory
copy of the original command is preserved for a later retry.  However,
a specific portion of the command state was not saved correctly, and
upon a retry this could lead to memory corruption.
