Pinnacle 300i antenna power kernel oops

Pinnacle 300i antenna power kernel oops

[Martin Konopka]

Hi,

after my failed attempts to activate the external antenna power on an Pinnacle 
310i, I bought a 300i. When I load the module saa7134_dvb with the option 
antenna_pwr = 1 I can indeed measure a voltage at the HF-Socket. But when my 
tv application tries to access the DVB device, I get a kernel oops. I have 
attached the log messages below. I'm using kernel 2.6.28-11-generic SMP 
i686 .

The card works perfectly when the antenna power is disabled.

Thanks for your help!

Martin

did not try to analyze the oops yet, but since the driver code for this
card is unchanged since years, I suspect it happens on a higher level.

You might try, if it still happens with recent v4l-dvb stuff.

In that case, Michael Krufky eventually can confirm it, since he is the
only one active on the lists currently having such a card.

Depending on what other stuff he is working on, this might be still time
consuming and an annoyance for him, but maybe he will have a look ;)

Btw, I received an used Pinnacle 310i this afternoon, since I'm a little
bit stuffed with mysteries on such.

First impression on recent:

The massive silver remote works, sometimes the driver fails to read the
eeprom on load. Else, it has 100% the same reception quality for analog
TV and DVB-T like all my other cards with tda8275a and without LNA
support and is totally stable.

I suspect now, that it is like on the HVR1110s currently, that we might
have already different models with and without LNA there too.

Cheers,
Hermann
