It looks like the I2C gate on the demod is closed, and the tuning code
is unable to reprogram the tuner. I don't know why off hand, I've never
used radio personally.
It also looks like the demod is also not responding to i2c read requests.
After this error occurs, does DVB-T and/or analog tv work correctly? Ie.
Does the problem clear itself.
Could be a GPIO issue which I could look into. Let me know the the
answer to the above question.
