Re: pinnacle pctv, can't tune since 2.6.10 (reverting bttv to 2.6.9's version fixes problem)

since 2.6.10 (till 2.6.11-rc2-mm2 tested last night), I can't change 
channels in any tv application.

dmesg shows things like :

Jan 30 06:03:55 localhost kernel: mt2032_set_if_freq failed with -121

Jan 30 06:03:56 localhost kernel: mt2032_set_if_freq2 failed with -121

Jan 30 06:03:56 localhost kernel: mt2032_set_if_freq failed with -121
I have heard that other french people has the same problem and also saw 
someone with a similar bug a few days ago on this list (with a mt2050 
this time).
I've hacked a 2.6.10 to work by reverting all bttv's related changes 
between 2.6.9 and 2.6.10, so it seems the bug have been introduced 
between these 2 kernels.
I'll be pleased to test any proposed patch, I already looked quite a lot 
at the patch I used to revert the changes but was not able to find the 
reason of the bug ...
Cheers,
Mik
