Subject: 11/780 crash

Has anyone had any experiences with the following
hardware fault on an 11/780.

We run 4.1bsd on an 11/780 with 2 meg,
2 RP06's, 2 Able DH/DM's, 2 DEC DZ11's.

problem:

cpu halts console spews :

	?INT-STK INVALID
	HALTED AT 8000xxxx
		      \   \
		       -------- random address

Problems is independent of system load, occurs
only with UNIX.  DEC diagnostics find nothing.

Page 40 of VAX hardware manual mentions error under
"serious system failures."
