    sys/bus/cam          cam_periph.c 
  Log:
  Put a bit of hysteresis into both BUSY SCSI status returns
  and CAM_RESRC_UNAVAIL returns. Delay a tunable amount for
  either between retries.
  
  This came up because the MPT IOC was returning "IOC out of
  resources" for some FreeBSD users and this caused a CAM_RESRC_UNAVAIL
  return. Putting a bit of delay between retries helped them
  out.
