In the past I have found unexplained failures of the sort you describe to
have resulted from bringing up a new version of the OS on hardware which
is of a sufficiently old rev. that the new software won't work on it.  I
would suggest contacting sun to check whether OS4.1 will run on your rev.
of the CPU and SCSI boards.
