Summary is basically NO you can not interupt a non-interuptable
state.  I was told to look at 
        1.) Scsi terminators--------> They are properly terminated
        2.) Cable connections--------> Connected
        3.) NFS mounted disks-------> this might be the
                        culprit I am mounting disks from a 
                        DEC 5000/240 with a prestoserve board is it
                        possible that this is to fast for the 
                        sparc2?  I will try to see if it only 
                        happens on NFS disks from that cpu.

Is there a way to interupt a process that has the status D
--- this is the status for non-interuptable ----
               D       Processes in non-interruptible waits;
                       typically  short-term  waits for disk
I have had tape drive jobs hang, give the process of D,
and then I have to reboot system to clear process/ drive
I have tried powering off drive, kill -(*)
where (*) was everthing I got from kill -l
I would appreciate any help on this.  The system is a sparc2
running SunOS 4.1.1
Tapedrives in question are cipher 1/2 inch and 8mm xbyte.
I have also had IDL die the same way.
