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.
No, I first checked that I was able to see DVB-T, and that worked without problems. Then I've started gnomeradio, and the errors were back into the dmesg. I've tried to restart the TV, but this gives now also :
[ 7744.066068] cx22702_readreg: readreg error (ret == -121)
[ 7744.066416] cx22702_writereg: writereg error (reg == 0x0b, val == 0x00, ret == -121)
[ 7744.066765] cx22702_readreg: readreg error (ret == -121)
[ 7744.067116] cx22702_writereg: writereg error (reg == 0x0c, val == 0x40, ret == -121)
However, I see only error messages for cx22702. Next I tried to unload the cx22702 module and to reload it. To remove it I also had to remove cx88_dvb. The modprobe failed however:

Could be a GPIO issue which I could look into. Let me know the the
answer to the above question.
I'm running AMD64 on Ubuntu (both edgy and Feist) and have Gentoo available if needed.
Let me know what info you need ...
