Should all be only saa7134 gpio related. I had a look at the diff you attached, and it made me a bit confuse. Most (all?) of it seem to be already applied in later kernels (>2.6.26), and they all fail on me. however, looking through the diff, I sumbled on the dprink's and I started to enable them on all modules I thought relevant. Here's a diff between the last -good and first-bad commit. The salient differences I can see is the "AGC2 gain" and the "setting GPIO22 to vsync 0". I have no clue what they mean, but my next step is to see if I can kill these differences. Is thee anything else in there which you find note worthy? Rgds, /Anders PS What is the tda829x doing? I see some differences there too. $ diff -u dmesg_2.6.25-03{6,7}* --- dmesg_2.6.25-03622-g1fe87369 2009-05-04 21:32:37.000000000 +0200 +++ dmesg_2.6.25-03774-g99e09ea 2009-05-04 21:37:06.000000000 +0200 @@ -42,14 +42,13 @@ tda829x 1-004b: tda827xa config is 0x01 tda827x: setting tda827x to system xx tda827x: setting LNA to high gain -saa7133[0]/core: setting GPIO22 to vsync 0 -tda827x: AGC2 gain is: 3 +tda827x: AGC2 gain is: 10 tda829x 1-004b: tda8290 not locked, no signal? tda829x 1-004b: tda8290 not locked, no signal? tda829x 1-004b: tda8290 not locked, no signal? -tda829x 1-004b: adjust gain, step 1.
