Bonjour,
je viens de faire une mise a jour de ma debian (installée il ya un an) et surprise : j'ai plus de tv (enfin plus d'image). La télé fonctionnait correctement avant l'upgrade.
les modules se chargent :
lsmod

videodev               10752  5 bttv
soundcore              11360  4 tvmixer,snd,bttv
 
par contre, dmesg me met un message inquiétant :

qq1 a une idée?

Passe en 2.6.8

en 2.6.8... tu pense que ca viens de ca?
ca marchait bien avant l'upgrade...
enfin pkoi pas...
je peux essayer!
 
je suppose que je peux réutiliser mon fichier .config?
il n'y a pas une version plus récente du noyau?

ca doit plutot etre un probleme de chargement des modules... ou d'option...
l'upgrade a mis a jour les fichiers de conf /etc/modules...
donc ca vient peut etre de la...
 

bon, j'avais du charger trop de modules la derniere fois...
 
bref, en chargeant i2c_core, i2c_algo_bit, videodev, tuner et bttv, ca me met ca :

mais toujours pas d'images
et j'ai toujours les messages d'erreur :
ioctl VIDIOCSYNC: Invalid argument
ioctl VIDIOCMCAPTURE(0,7,384x288): Invalid argument
ioctl VIDIOCSYNC: Invalid argument
...
 
je n'ai pas mis le noyau 2.6.8... ca me parait pas utile étant donné que ca fonctionne avec ce noyau, il faut juste faire un peu de conf! --> il faut quoi dans les fichier /etc/modules*???

2.6.12 out là (car bon, le 2.6.6 ça date quand même ).

je viens d'essayer un 2.6.8 et la télé fonctionne
par contre, je ne peut plus aller sur le net
-> les drivers de linuxant (hsf) ne s'installent pas!
donc je suis coincé
qq1 a un driver pour modem pci qui fonctionne?

alors ca y es, j'ai réussi (pas sans mal) a install les drivers de linuxant!
il fallait peut etre que x ne sois pas lancé pour que ca passe?!
bref je peux aller sur le net avec mon 2.6.8 ...a 14kb/s
et la tv fonctionne
j'espére ne plus avoir de mauvaise surprise...
