Ah well here was the oops:

 <0>Kernel panic: Aiee, killing interrupt handler!

1 warning issued.  Results may not be reliable.



And it was not in 2.4.23-pre5 it was in pre3 that it started to happend,
so try 2.4.23-pre2, se below:




Now I have tested kernel versions starting from 2.4.22 and the result is 
as below:


2.4.22                                          =  works ok!
2.4.22      plus 30_bttv-0.7.x-2.4.23-pre6.diff =  works ok!
2.4.22-pre2 plus 30_bttv-0.7.x-2.4.23-pre6.diff =  works ok!
2.4.22-pre3 plus 30_bttv-0.7.x-2.4.23-pre6.diff =  NOT OK -> Oops!


So my conclusion is that something was changed between -pre2 and
-pre3 that made the kernel oops with the 30_bttv-0.7.x-2.4.23-pre6.diff
patch added.
