Joakim, attached is a TGZ with some test binaries.  I'm assuming the
"imd" will print one device while "mnp" another.  This is mostly to
firm up which devices it's actually trying to use.  Based on your
other results, this should help a little more to understand how the
code is reacting to your machine.  It won't give me an answer but just
lead me towards the next step.
