scp a 600MB ISO from machine A (wired to the AP) to machine B (libertas
CF Ambicom WL54-CF).  Machine B is a Fujitsu Lifebook 1510P.  Stalls
about 5 seconds into the transfer.  Could be the controller at fault,
but I don't have a second machine handy with a CF slot.

So if you've tested it and feel comfortable with the stability on CF,
should we push to linville then?
