[linux-dvb] cx8802_timeout during DVB streaming

[Andrew de Quincey <adq_dvb@lidskialf.net>]

Hi, I remember Steve mentioned these - I'm seeing them too (full log after this). I 
think they're only happening when the demodulator is retuned - my guess 
is it stops outputting any data during a retune, so the cx88 times out.
