cp read fault (4.2BSD on VAX 780)

[Chris Torek]

In artcile <1824 at brl-smoke.ARPA> kjs%tufts.csnet at csnet-relay.arpa
asks for help in tracking down a `cp read fault' machine check.

Look at the program counter (`pc') value and see in which routine
you were running.  That can be a useful clue; e.g., if you are in
dmf.c, it is probably a DMF (or of course all the access paths
all the way out to the device).  The `va/viba' register gives the
virtual address the machine was working on when it got the read
fault.
