It seems the i2c gate control of the tda8290 at 0x96 is broken in DVB-T mode open/close related. Correct behavior with current mercurial tuning the tuner at 0xc0. saa7133[0]: i2c xfer: < 10 06 [fd quirk] < 11 =af > saa7133[0]: i2c xfer: < 10 06 [fd quirk] < 11 =af > saa7133[0]: i2c xfer: < 10 06 [fd quirk] < 11 =af > saa7133[0]: i2c xfer: < 10 01 [fd quirk] < 11 =91 > saa7133[0]: i2c xfer: < 10 01 91 > saa7133[0]: i2c xfer: < 10 02 [fd quirk] < 11 =1c > saa7133[0]: i2c xfer: < 10 02 1c > saa7133[0]: i2c xfer: < 10 03 [fd quirk] < 11 =00 > saa7133[0]: i2c xfer: < 10 03 00 > saa7133[0]: i2c xfer: < 10 43 [fd quirk] < 11 =03 > saa7133[0]: i2c xfer: < 10 43 03 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 00 2e 70 00 16 14 4b 1c 06 24 00 > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 90 ff 60 00 59 > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 a0 40 > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c1 =09 =a8 > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 c0 99 > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 60 3c > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 30 11 > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 c0 39 > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 50 4f > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 10 01 [fd quirk] < 11 =91 > saa7133[0]: i2c xfer: < 10 01 91 > saa7133[0]: i2c xfer: < 10 02 [fd quirk] < 11 =1c > saa7133[0]: i2c xfer: < 10 02 1c > saa7133[0]: i2c xfer: < 10 02 [fd quirk] < 11 =1c > saa7133[0]: i2c xfer: < 10 02 1c > saa7133[0]: i2c xfer: < 10 03 [fd quirk] < 11 =00 > saa7133[0]: i2c xfer: < 10 03 00 > saa7133[0]: i2c xfer: < 10 31 54 > saa7133[0]: i2c xfer: < 10 32 03 > On the broken 2.6.29.1 it looks like that. saa7133[0]: i2c xfer: < 10 22 [fd quirk] < 11 =ff > saa7133[0]: i2c xfer: < 10 21 [fd quirk] < 11 =ff > saa7133[0]: i2c xfer: < 10 20 [fd quirk] < 11 =ff > saa7133[0]: i2c xfer: < 10 01 [fd quirk] < 11 =91 > saa7133[0]: i2c xfer: < 10 01 91 > saa7133[0]: i2c xfer: < 10 02 [fd quirk] < 11 =1c > saa7133[0]: i2c xfer: < 10 02 1c > saa7133[0]: i2c xfer: < 10 03 [fd quirk] < 11 =00 > saa7133[0]: i2c xfer: < 10 03 00 > saa7133[0]: i2c xfer: < 10 43 [fd quirk] < 11 =03 > saa7133[0]: i2c xfer: < 10 43 03 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 00 32 c0 00 16 5a 5b 1c 06 24 00 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 90 ff 60 00 59 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 a0 40 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c1 =09 =a8 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 c0 99 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 60 3c > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 30 10 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 c0 39 > saa7133[0]: i2c xfer: < 96 21 c0 > saa7133[0]: i2c xfer: < c0 50 5f > saa7133[0]: i2c xfer: < 96 21 80 > saa7133[0]: i2c xfer: < 10 01 [fd quirk] < 11 =91 > saa7133[0]: i2c xfer: < 10 01 91 > saa7133[0]: i2c xfer: < 10 02 [fd quirk] < 11 =1c > saa7133[0]: i2c xfer: < 10 02 1c > saa7133[0]: i2c xfer: < 10 02 [fd quirk] < 11 =1c > saa7133[0]: i2c xfer: < 10 02 1c > saa7133[0]: i2c xfer: < 10 03 [fd quirk] < 11 =00 > saa7133[0]: i2c xfer: < 10 03 00 > saa7133[0]: i2c xfer: < 10 31 60 > saa7133[0]: i2c xfer: < 10 32 02 > saa7133[0]: i2c xfer: < 10 33 aa > saa7133[0]: i2c xfer: < 10 34 aa > saa7133[0]: i2c xfer: < 10 35 ab > saa7133[0]: i2c xfer: < 10 4d 0c > saa7133[0]: i2c xfer: < 10 4e 00 > saa7133[0]: i2c xfer: < 10 16 [fd quirk] < 11 =a8 > saa7133[0]: i2c xfer: < 10 16 a8 > saa7133[0]: i2c xfer: < 10 01 [fd quirk] < 11 =91 > saa7133[0]: i2c xfer: < 10 01 91 > saa7133[0]: i2c xfer: < 10 02 [fd quirk] < 11 =1c > saa7133[0]: i2c xfer: < 10 02 1c > Mauro had a fix during further changes for the upcoming 2.6.30 commits on mercurial, but it seems to be broken already previously. The open gate, write to tuner, close gate commands are no longer in the also previously known sequence and might cause the trouble visible on the saa713x.
