 I tried with 2.6.31 vanilla and again had the same problem: if femon was
 started before mythtv-setup, the scan was ok, if started femon at a later
 time, no channels were found.

 I have tried the patch/revert to cx88-dvb.c mentioned in that thread and
 that seems to do the trick for me as well. I can watch TV again.
 For now it seems that tuning takes a bit longer than before because I get
 the channel lock warning which I did not see with earlier kernels. After a
 few seconds, however, the picture appears.
 I will keep an eye on this.

 BTW, http://svn.mythtv.org/trac/ticket/7292 seems to be about the same

 > it should only affect 2.6.29+ though

 Judging from the time the change was made it could have been 2.6.27 as
 well, but I am no git expert and cannot determine when it actually went
 into mainline.

 What is the correct way to proceed now? Wait for a kernel patch?

 In any case, thanks for your help!
