[linux-dvb] kernel oops

[Antonino Sergi <voyaser@tiscalinet.it>]

Hi all, 

I have a Nexus-s (rev 2.2) with CI module (rev 1.6) and aston cam seca
rev 1.05 

The hardware works fine (tested under win). 

If I use the cvs snapshot 20020702 "everything" works fine, except that
CI module is not detected. 

If I use a more recent driver (20020727) the result is (insmod options:
init_chan=2 pids_off=0 debug=1 and fdebug=1):

The problem seems to be before card initialization!? (otherwise I should
have seen at least something like:
