I seem to have isolated the problems with SMP on this machine to the
built-in Intel Pro/1000 (82540) Ethernet interfaces.  The machine *nearly*
freezes after ifconfig is run during startup.  It can respond to the
keyboard
(accepting characters) the first few times I unplug/plug the Ethernet cable
from em0 and cause link down/up messages on the console.  This only works a
few
times before the keyboard becomes completely unresponsive.  I've tried a
4.8-RELEASE
and a 4.9-STABLE kernel cvsuped today.  Any suggestions would be
appreciated.
