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