The machine works fine with 3.19.0-16, which I built with one extra
commit for bug 1448942. Since that fix has since been merged in
master-next I was trying to test a newer kernel to see when I can get
back out of the business of building my own. My first try failed due
to a hang that was later fixed by commit 1ece1db, and my second try
left me here.
