694 When this option is set to a non-zero value, the driver checks SCSI lines
695 logic state, 100 micro-seconds after having asserted the SCSI RESET line.
696 The driver just reads SCSI lines and checks all lines read FALSE except RESET.
697 Since SCSI devices shall release the BUS at most 800 nano-seconds after SCSI
698 RESET has been asserted, any signal to TRUE may indicate a SCSI BUS problem.
699 Unfortunately, the following common SCSI BUS problems are not detected:

715 devices. If unfortunately you have SCSI problems, you can check the
