No Joy.

Disabled the on board NIC and plugged in a couple of different NICs in
different PCI slots - and they were all just as bad as the one on the
motherboard.  Let it rest unplugged overnight (just in case it was a
stuck bit) and it didn't recover.  Loading the PCI graphics card also
crashed it.  Seems like a failing circuit in the chipset in or around
the PCI bridge.  First time I've seen that failure.  Replaced that
motherboard with an even older one, a tiny bit slower, but still working.
