I have installed SCO OpenServer Release 5.0.4 and Release
          Supplement 504C (rs504c) onto a system with two SCSI host
          adapters.  When I execute the command "sconf -v", the system
          panics with "trap type 0x0E."

          If I remove the Release Supplement 504C, or only have one SCSI
          host adapter configured, this panic does not occur.

          A stack trace using crash(ADM) indicates that the panic occurred
          within the Scfgioctl kernel routine.  For example:

   # crash
   > trace

          In order to prevent this panic, add the boot option "scsi.noscan"
          (see bootstring(HW) for details) to the DEFBOOTSTR entry in the
          file /etc/default/boot.  For example:

                DEFBOOTSTR=hd(40)unix scsi.noscan

          Reboot the system for this change to take effect.
