Gentoo. I've had no problem with all kernels up to 2.6.29. Then I tried to upgrade to the 2.6.3x. The problem is quite strange. My TV-card which is PCMCIA Avermedia E500 based on SAA7134 chipset requires custom tuner parameter (for Alps tuner): # modprobe saa7134 card=46 tuner=12 With 2.6.3x kernel it seems that the 'tuner' parameter is ignored and for all settings the tda9887 is selected (which is a wrong one and disallows watching TV). /var/log/messages for older kernel: Sep 19 23:00:58 entoo saa7130/34: v4l2 driver version 0.2.14 loaded Sep 19 23:00:58 entoo saa7134 0000:07:00.0: enabling device (0000 -> 0002) Sep 19 23:00:58 entoo saa7134 0000:07:00.0: PCI INT A -> Link[LNKB] -> GSI 5 (level, low) -> IRQ 5 Sep 19 23:00:58 entoo saa7133[0]: found at 0000:07:00.0, rev: 209, irq: 5, latency: 0, mmio: 0xc8000000 Sep 19 23:00:58 entoo saa7134 0000:07:00.0: setting latency timer to 64 Sep 19 23:00:58 entoo saa7133[0]: subsystem: 1461:b6e8, board: AVerMedia Cardbus TV/Radio (E500) [card=46,insmod option] Sep 19 23:00:58 entoo saa7133[0]: board init: gpio is 0 Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom 00: 61 14 e8 b6 ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom 10: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom 20: ff d1 ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom 30: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom 40: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom 50: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom 60: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom 70: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom 80: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom 90: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom a0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom b0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom c0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom d0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom e0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo saa7133[0]: i2c eeprom f0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff Sep 19 23:00:59 entoo tuner' 5-0042: chip found @ 0x84 (saa7133[0]) Sep 19 23:00:59 entoo tda9887 5-0042: creating new instance Sep 19 23:00:59 entoo tda9887 5-0042: tda988[5/6/7] found Sep 19 23:00:59 entoo All bytes are equal.

Finally solved... For all kernels till 2.6.29 I loaded the driver with: modprobe saa7134 card=46 tuner=12 and it worked OK (E500 + AlpsTSBE5) For kerneks 2.6.30+ that command loaded card 46 and wrong tuner (E500 + TDA9887). But I finally discovered that: modprobe saa7134 card=158 tuner=12 works OK (E501R + AlpsTSBE5). Seems like my card used to be detected as E500 and now it is detected as E501R and setting it to E500 results in loading wrong parameters. Very funny... ;-(
