After checking the datasheets of Thompson tuner, and I have one

At board description, tda9887 is not there. This tuner needs to work

This small patch does enable it for your board.

You should notice that you may need to use some parameters for
tda0887 to work properly, like using port1=0 port2=0 qss=0 as insmod
options for this module. (these are some on/off bits at the chip, to
enable some special functions - if 0/0/0 doesn't work you may need to
test 0/0/1, .. 1/1/1).


This has fixed it for me!! I compiled todays cvs, with out this patch,
to watch it fail, then added the line as noted, and reloaded the
modules without rebooting, and it worked. I did a cold start to see
that it is repeatable, and it continues to work. I used no extra
parameters, so the defaults are working fine.



I haven't built it yet, had to apply the patch by hand for some reason
here, after doing a cvs up -D today.

2.6.15-rc4 under construction to test it.

Gene, dont bother applying the patch to the cvs code -- It is obviously correct, so I have merged it into v4l-dvb cvs.

A simple cvs checkout will get you everything you need.

If you like, try to apply it against the kernel, without using cvs.

Anyhow, surely it will work. Thank you Gene, Don and Perry for helping us to solve this bug......... Hopefully we'll be able to get the fix into 2.6.15.

Cheers,

Michael Krufky
