Hi,
i have the leadtek winfast tv2000xp expert tv card. it uses the
cx8800/xx drivers.
when i install a v4 kernel, when the de loads up a screeching sound
starts (https://dl.dropboxusercontent.com/u/17100344/Debian.wav). this
doesn't happen on the v3.17 kernel i am currently running. also on the
v4 kernel when i blacklist cx8800 this does not happen.
some things i have ascertained is that on the v3.17 kernel, this is what
lsmod shows:
$ lsmod | grep cx88
cx8800 31477 0
cx88xx 80236 1 cx8800
btcx_risc 4192 2 cx8800,cx88xx
tveeprom 14712 1 cx88xx
videobuf_dma_sg 10902 2 cx8800,cx88xx
rc_core 20852 3 cx88xx,rc_winfast

videodev 148569 6

videobuf_core 19391 3 videobuf_dma_sg,cx8800,cx88xx
i2c_algo_bit 5789 2 cx88xx,nvidiafb
i2c_core 44594 16

this what kernel 4.0 shows
$ lsmod | grep cx88
cx8800 27673 0
cx88xx 80070 1 cx8800
tveeprom 15352 1 cx88xx
videobuf2_dma_sg 8585 1 cx8800

videodev 146932 7
tuner,cx8800,cx88xx,gspca_main,v4l2_common,videobuf2_core,gspca_zc3xx
i2c_algo_bit 5846 2 cx88xx,nvidiafb
i2c_core 45327 16

i am wondering whether the difference lies in the missing btcx_risc?
$ cat /boot/config-4.0.0 | grep BTCX
j$ cat /boot/config-3.17-4.dmz.2-liquorix-amd64 | grep BTCX
CONFIG_VIDEO_BTCX=m
i don't have much knowledge in the ways of the kernel so your guidance
would eb appreciated.
Kind regards
