I got replies from two. The solution is to upgrade to the latest IPI
controller if the problem occurs again. B.Rea@csc.canterbury.ac.nz had
already posted his summary to this list for a similar problem. Thanks to
those who replied.

Two solutions to similar problems were the replacment of the CPU board (Terry Rosenbaum) and upgrading to the lastest IPI controllers (Ira Winston).

We had errors like this after adding an S-bus controller to a recently upgraded 670MP running SunOS 4.1.2. Occasionally, however, the system would hang and when re-booted there were problems with the file system which fsck would not correct. The problem became so severe that we are not using the IPI disk sub-system. Instead, we had to re-construct our system on new SCSI disks which were purchased at the same time as the 670 upgrade.
We are waiting a decision from SUN Canada on what our next step will be.
