[Hackrf-dev] Ok, this is weird

So after setting aside my HackRF for a bit while I worked on other things,
I picked it up today and started working on my FM experiments. I got a
bazillion analog underruns. I went back to the original class version of an
FM receiver and its giving me underruns now as well.

The underruns make the system continually burp which is not good. I do
regular system updates but there isn't anything pending that requires a
reboot. I've unplugged and replugged the HackRF 1,  It is running 2015.07.2
firmware. I'm pretty sure I updated the CPLD at the same time and tested it
afterwards and it was fine then.

So what I'm wondering is the process to use to start narrowing down the
issue.
