Sorry, I think I missed it: Do you use the drivers from dvb-kernel CVS 
or from the kernel?

I really can't imagine why it locks up. The driver "only" passes the 
transport stream to the software demuxer from the API. And it controls the 
PID filter of the Flexcop Chip. Do you have SMP?

Please load the b2c2-flexcop.ko module with debug=0x09 to see if the PID 
filter-settings are correct.

Also you could try to load the b2c2-flexcop-pci.ko with 
enable_pid_filtering=0 (default is yes). Maybe it is an unkown bug with 
the pid-filter-routine (I don't think, since a lot of people (incl. me) 
are using it successfully).
