Your two problems are not the same.  Kevin's is probably, as he points out,
happening at auto-config time, or thereabouts.  Actually, it's probably
dying when it tries to do something like enable the cache or check for
the '881 ( I remember reading that this happens right before the workbench
screen comes up ) ...

Your problem is something more like I had.  It is basically one of flakiness.
I built the bus terminator and it bacame quite solid.  As you say, mine
was dying: when I tried to loadwb, when it got a requestor, etc.
Anything that was CHIP-MEM related ( it seemed ).  And always with an
f-line instruction.

Now, it just hangs when I put my Supra on and try to "supramount".  If
I just let the Supra sit (no mount) it will die eventually, with very
wierd errors.

Sigh.
