[linux-dvb] Kernel panic with AverMedia and latest v4l/dvb-kernel

[Itai Tavor <itai@iinet.net.au>]

Hi people,

So I had myself a working system with an AverMedia DVB-T, kernel 
2.6.8.1 and the standard kernel v4l and dvb modules. And what does one 
do with a perfectly working system? Correct - one messes with it.

So I added a second tuner - a Dvico FusionHDTV DVB-T Lite this time. Of 
course, it isn't supported by the kernel dvb code, so I installed 
dvb-kernel from cvs. That also required a newer v4l, so I got the 
latest snapshot. Then I removed the original kernel v4l and dvb modules 
and built and installed the new modules.

My punishment was swift but fair, and came in the form of the kernel 
panic seen in the end of the log output below. I tried the same process 
with kernel 2.6.9 and with a slightly older v4l snapshot, with the same 
result.

Any help? Any Ideas?

TIA, Itai
