SUMMARY: iinactive crash on 690

We have had two system crashes since we upgraded from a 490 to a 690.
The panics are below.

The system is
690 - 2 CPUs
SunOS 4.1.2. no patches
2 x 1Gb IPI disks
2.3 Gb Exabyte Tape
150 Mb 1/4 inch tape
Sun CDROM
I recieved two replies.

The first crash may have been due to an out of rev IPI controller. There
is an incompatibility between the multiprocessor models and the earlier
revisions of the IPI controller. The controller revision level needs
to be -07 or higher on the old controller. To complicate matters there
is a new IPI controller which has a new part number. It was one of these
new boards that was installed between the first and second crashes. The
revision level on our currect controller is -03, which I am told is
equivalent to rev -09 on the old controller. Usually the system would
hang rather than crash when the older controller gave problems.

This bothers me as I *never* omit the file system checks when booting the
system. A change that has taken place in SunOS 4.1.2 in that quickcheck is
now part of the system and not an optional extra. Quickcheck certainly
saves a lot of time during boot.
I have turned on savecore so that if we get another panic like this
there will be something to look at.
