I just want to say that I got the older cards working on Ubuntu 16.04 LTS as I wanted to on two different PC motherboards including the HP Gen8 server. I even have 4 SDI inputs from a Decklink Duo, and Extreme 3D and an Extreme 3D+ all working together.
I did do firmware upgrades on all of the cards and used the latest drivers. All inputs worked in OBS. On top of that, bmdtools/bmdcapture worked like a charm with ffmpeg.
I thought I'd share that to give some users hope.
