I had the same problem. I have mentioned it on the list but never got any 
answer :( 
My card was sharing its IRQ with my onboard Ethernet controller. When I 
plugged my 
Pinnacle PCTV Sat CI into another PCI slot (IRQ sharing with an onboard USB 
hub) the error disappeared. 
Now dvb-bt8xx seems to load correctly but unfortunately I get another error 
when loading the module dst. 
Maybe it is still a IRQ problem? 
 
Here is the output of dmesg:

Maybe you should try to plug your card into another PCI slot?
