OK, I think I have bottomed out the source of the issues. As part of the
tests to see if the tuners are present, the backend sets the device to a
channel, and then after confirming the device is accepting commands, sets
the channel AND frequency to 0.

In my tests, it seems that setting the frequency to 0 causes the tuner to
fail, a high percentage of the time, and it only comes back with a power
cycle. I've confirmed this from the web interface by setting to a channel,
confirming lock, then tuning to 0/0, waiting, then tuning back to the
channel. JUST changing the channel seems to not cause the issue.
