Re: Kernel Oops with Kernel 2.6.32
Hello, The value for adap is in register RDI: 0002, and that is not a valid pointer. There is a bug in dib7000p.c somewhere. Do a 'hg log -v -p linux/drivers/media/dvb/frontends/dib7000p.c | less' to see what might have changed. I cannot find the reason for the Kernel Oops. I even copied the dib7000p.c from an April 2009 version and just added two missing necessary functions (dib7000p_pid_filter_ctrl and dib7000p_pid_filter), but the Kernel Oops does still occur.

Re: Kernel Oops with Kernel 2.6.32
Hello, Can really nobody give me an advice what I can do to make my Nova-T-Stick work with my Debian Kernel 2.6.32? I want to add the information that I had it working with my Debian Kernel 2.6.26 and sources from linuxtv.org which I downloaded on April 09, 2009. Regards Christoph Hello, I am running a Debian 2.6.32-Kernel (which by the way contains a lot of unresolved symbols in many dvb modules). As this kernel does not support my WinTV Nova-T USB-Stick, I downloaded the latest sources via the web interface from linuxtv.org, compiled the sources and installed the resulting modules. When I now connect the USB stick, the DVB modules are loaded correctly, but when I start an application to watch TV, I get a Kernel Oops.
