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!
