Well, I did say "seems to".  :)

igb+lagg worked for us on 8.3.  Haven't tried it since moving to 9.0
and 9-STABLE on those three boxes.

igb+lagg doesn't work for him on 9.0.  Although, I don't recall if
non-LACP options were tried earlier in this thread, or if it's just
the LACP mode that's failing.  If one mode works (say failover) and
LACP mode doesn't, that "seems to" point to lagg.

I'll see if I can free up an igb port on my 9.0 and 9-STABLE boxes to
test this with as well.
