	Okay I've got the latest version from CVS and so I compiled it and 
installed the new drivers. To make sure that I have a clean system, I 
rebooted and modprobed the new drivers. After using dvbtune to set the 
T-DSL sat frequence and to open the network device, everything seemed 
alright to me. dvbtune said that the network device has been opened 
successfuly and that it should be configured now - this didn't happen 
before.

But when I tried to set the IP address of the new dvb0_0 interface, I 
got a segmentation fault.
# ifconfig dvb0_0 192.169.0.99

I couldn't rmmod the bt8xx module anymore and every time I tried to run 
ifconfig -a dvb0_0 the console hung and the process couldn't be killed 
by either Ctrl + C or kill <pid>. After rebooting the system manually, I
tried
# ifconfig dvb0_0 hw ether 00:01:02:03:04:05
which worked fine. But always when I try to set the IP address I get a 
fatal segmentation fault.

Here is the last dmesg output I got after configuring the net device:

bttv0: IRQ lockup, cleared int mask

I don't know whether this helps you..

Thanks again,
