	Hey ho (again)....

	My original problem concerned a second Etherboard (CMC ENP10)
in the VME slot of a 4D/25.  We were observing "enp0: died and restarted"
and, in extreme cases, kernel faults due to bus errors.  This latter
usually accompanied attempts to ftp files over the interface in question.

	Swapping the board with a new one has cured the problem.  All 
works well now.  However, for those considering installing a second
board in a PI, I have one comment to make: 

	The physical design of the board is lacking.  The surface of the
board, as it rises above the connector backplane, extends 1.5" closer to
the back of the cabinet than normal.  Consequently, once the standard SGI Ether
cable is installed, you don't have a hope in hell of closing the box
again.  The only reasonable solution is to get ahold of an Ether cable
with a 90 degree angled head.  DEC makes a suitable one; they are 
fairly rare.

Regards,
                             _ _         _ _
