Hi,

I've bought the Terratec Cinergy 1200 DVB-T and have problems to get it 
running.

I'm using Kubuntu Gutsy (amd64) with the 2.6.23.1 vanilla kernel (The 
official kernel in the repos is very very buggy, so I don't want to try 
it out there). Tried adding the modules in menuconfig and building them 
as described here 
http://www.linuxtv.org/wiki/index.php/How_to_install_DVB_device_drivers 
too. I always get the same error in dmesg:

saa7146: register extension 'budget_av'.

It looks like the tda1004x-module is missing, but it isn't. It's also 
loaded:

The frontend device-node is missing, everything else is there:
$ ls /dev/dvb/adapter0/
ca0  demux0  dvr0  net0

Also installed WinXP to try it out there and it's working fine, so it's 
no hardware-problem.


Is this a bug (probably only on amd64 kernels) or am I just too stupid 
and did forget something?


Thanks in advance,
Oliver Haag
