Description of problem:
Up to kernel-2.6.25.14-69.fc8 my Terratec Cinergy 1200 DVB-C card was working fine  in VDR. After updating to kernel-2.6.26.5-28.fc8 the card is not found anymore, i.e. I see no messages for this card in /var/log/messages. Two other DVB-T cards still remain working.

Comment 1 Markku Kolkka 2008-10-03 13:39:26 UTC 
I have the same card and the same problem. With kernel 2.6.25.14-69.fc8 the device nodes in /dev/dvb/* aren't created even if lsmod shows that the driver modules for the card are loaded. From system log it appears that the new kernel thinks that the DVB-C card is a sound card:

Blacklist the snd-aw2 driver by adding it to /etc/modprobe.d/blacklist
