>Release:        4.1 kern.flp and mfsroot.flp
>Organization:
DOD - EDS Contractor.
>Environment:
This is a fresh install on a Compaq Proliant 5000R with two (2)
Compaq SMART-P Array Controllers and four (4) Pentium Pro 200 Mhz
processors.  These SCSI array controllers previously worked fine with
SCO Openserver 5.0.
>Description:
The kern.flp is booted, then mfsroot.flp is read and the hardware list
is displayed.  Hardware is deleted to match our equipment and we Quit
the list.  Within 1 second, numerous probes are displayed .... and when
the probes reach the ida1 ( the second SMART-P SCSI controller) the
kernel panics with TRAP 18 , interger divide fault.

instruction pointer 0x8:0xc015a4f2
   .
   .
   .
......numerous other important details scroll off the screen
and flash ... the screen goes blank ... as the system reboots.
To isolate the fault .... the second SMART-P SCSI controller was physically
removed from the system.  This time, the color FreeBSD installation
screen was displayed!  No crash.  Then, the SMART-P SCSI controller was re-installed
and the same crash occurred at the same sequence with the same value
of instruction pointer.  Sorry we could not gather all the other details,
as they flash on the screen.
>How-To-Repeat:
Use the 4.1 kern.flp and mfsroot.flp on a Compaq Proliant 5000R with
two SMART-P SCSI Array controllers.  Boot and follow steps to install.
Very repeatable.
>Fix:
Compaq has a customer advisory # EU000322_CW01 that describes similar,
but not identical, problems with two add-on SCSI controllers running Solaris.
