problem with vax console rev 7

[P. T. Withington]

We have a 4.1/780 with rev. 7 console and occasionally get double cpu error
halts.  If we don't get a halt, the boot dies with a format error trying to
read /.  These problems go away after running DEC disk diagnostics.  Therefore
my *guess* is that something is not reset in the disk controller by boot.  I
would appreciate any light others can shed on this, since I have not had a
chance to dig into it yet.

(Our disk is an RP-07, we also have the new memory controller.)
