[ATrpms-users] Latest FC3 v4l2 drivers and bt878 / bttv fun and games

[AlanM]

Hi all,

Please can someone help or give me some pointers on this...

I have been trying to get my backend rebuilt using FC3 and using apt-get 
for everything ie not recompiling kernel and other things as I usually 
end up doing!

Using 2.6.11-1.27_FC3 All I have to do is: modprobe dvb-bt8xx

and in dmesg I get the lovely...
DVB: registering new adapter (bttv0).
DVB: registering frontend 0 (NxtWave NXT6000 DVB-T)...

However I also have a Nova T 9002 card (cx88). After much googling and 
general messing around I found I have to:
[root at staging-be mythtv]# apt-get install cx88
....snip...
   1:video4linux-kmdl-2.6.11########################################### 
[ 25%]
   2:cx88-kmdl-2.6.11-1.27_F########################################### 
[ 50%]
   3:video4linux            ########################################### 
[ 75%]
   4:cx88                   ########################################### 
[100%]
and also
[root at staging-be mythtv]# apt-get install bttv
and
[root at staging-be mythtv]# apt-get install saa7134
(quite why the last one I am not sure but get mt352 complaints about 
versions if I don't)

Now the Nova works fine :)
However the NXT has stopped working!  :(  (The same if I remove the Nova)

The error I get:
modprobe dvb-bt8xx
FATAL: Error inserting dvb_bt8xx 
(/lib/modules/2.6.11-1.27_FC3/kernel/drivers/media/dvb/bt8xx/dvb-bt8xx.ko): 
Unknown symbol in module, or unknown parameter (see dmesg)

dmesg:
dvb_bt8xx: disagrees about version of symbol mt352_attach
dvb_bt8xx: Unknown symbol mt352_attach
dvb_bt8xx: disagrees about version of symbol bttv_sub_unregister
dvb_bt8xx: Unknown symbol bttv_sub_unregister
dvb_bt8xx: disagrees about version of symbol bttv_sub_register
dvb_bt8xx: Unknown symbol bttv_sub_register
[root at staging-be mythtv]#

Its that mt352 thingy again :\



Is there something else I have to modprobe that I have missed out, or 
does the rewritten bttv currently have a problem? I read it " requires a 
kernel with v4l2-api patch applied" does this mean I can't get away 
without recompiling? Or am I waiting for 2.6.12... for all this to be 
incorporated (as I seem to remember reading somewhere)


Please help...

Alan

Relevant bit of dmesg with both cards installed. Nova working, bttv 
Nebula NXT6000 not...
