Description Michael Heijenga 2012-04-19 19:23:48 UTC 
Description of problem:

Bug 808871 - DVB-S is broken since kernel 3.3 
Some TV cards outside still not working with 3.3 but work with 3.2

How reproducible:
# uname -a
Linux fc1664 3.3.2-3.fc16.x86_64 #1 SMP Tue Apr 17 22:20:47 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Switch from one DVB-S channel to another, some channels are good, some still broken in video and sound. It is not DVB-S DVB-S2 mode switching I think, because the card is no DVB-S2 card. Bug 812895 - Bug in dvb driver modules when switching from DVB-S2 to DVB-S.

Steps to Reproduce:

1. boot the pc, dmesg:

did this: https://bugzilla.redhat.com/show_bug.cgi?id=812895#c1
Then post here the dmesg before calling caffeine, ... done

2. start kaffeine and choose a 'good' channel

here DVB-S TV is fine


Actual results:
DVB-S not working with kernel 3.3, still works with kernel 3.2

Expected results:
DVB-S working with kernel 3.3

Additional info:
I'm not sure if this is helpfully bit i will try to go with your advice!
