Description ben 2007-07-07 16:50:22 UTC
I tested my previous kernel 2.6.19-r5 side by side with 2.6.20-r8. The /dev/dvb nodes are populated correctly in 2.6.19-r5 but not in 2.6.20-r8. The dvb configurations are identical as confirmed by manually comparing the two .config files.

I'm using Hauppauge WinTV Nova-T (model 909).Specifically, the Conexant chipset.
I generally followed this forum thread for configuration:
http://forums.gentoo.org/viewtopic-t-266245-highlight-linuxtvdvbapps.html?sid=a55547658885b31563fd3a1fa0027dcb

Reproducible: Always

Steps to Reproduce:
1. Compile kernels with my dvb configuration.
2. Start pc with said configurations.

Actual Results:  
In 2.6.19-r5 the /dev/dvb nodes should be present.
In 2.6.20-r8 the /dev/dvb nodes will not be populated.

card is detected and driver loaded as is the case for 2.6.19-r5, however, the adapter and frontend are not registered with 2.6.20-r8.

You need to load the cx88-dvb module

It works if i load that module manually. But i don't understand why it didn't autoload it like it does for 2.6.19-r5.
