Hello!
Allan,
I've applied your patch as well as the 6 patches you have mentioned in
your post against a 2.6.12.2 kernel.
Modules loaded as before, but the result is not better.
scan with Astra-19.2E does find some channels now, but there are lots of
doubles and also lots of tuning failed messages.
there are lots of messages in the kernel logs now, even without any
debug options set. I've added an excerpt at the end of the mail.
---------------------
Another Problem i have seems to arise from the combination of the
Twinhan card with an old analog Haupauge WinTV card, which i had removed
for the tests in my first mail.
When both cards are in place, sometimes the dst module isn't able to
initialise or something. I think this mainly appears, when the analog
card is detected as the first card, but sometimes also if they are the
other way round, as in this case (debug options enabled):
--snip--
Jul 10 13:08:26 okibil kernel: DVB: registering new adapter (bttv0).
Jul 10 13:08:26 okibil kernel: write_dst: write_dst error (err == -5,
len == 0x08, b0 == 0x00)
Jul 10 13:08:29 okibil last message repeated 3 times
Jul 10 13:08:30 okibil kernel: dst_check_ci: write not successful, maybe
no card?
Jul 10 13:08:30 okibil kernel: dvb-bt8xx: A frontend driver was not
found for device 109e/0878 subsystem 1822/0001
--snip--
I now have the Twinhan DTV detected as first card. When i now access the
radio0 device i get Ooops, television works, as long as i don't use
radio. It doesn't matter here, whether dvb_bt8xx and dst are loaded or
not.

I want to figure this thing out further, but first i'll try a patch from
http://linuxtv.org/downloads/patches/2.6.12/ and maybe 2.6.13 with cvs.
Greetings,
Robert
