System V is Crashing

A colleague of mine is trying to bring up AT&T's UNIX System V on a VAX
11/780.  Periodically, the system will crash and halt the CPU with the
following message:

Machine software error: Protection violation on interrupt stack.

AT&T insists that the crash is due to a hardware error.  However, this
same VAX can run UNIX 4.1BSD and VMS with no problems.  Any clues to the
cause of this problem would be immensely appreciated.

Thank You,
