My struggle for working knc1-dvb-c goes on.
The thing works under windows but not under linux.

I have now put the card into a different machine because the one I was
using earlier was an athlon 64 with 64bit kernel and userland. To make
sure that this was not the problem I'm now trying it on a 32bit kernel
machine (still an athlon 64 tho). The machine has a fresh installed
kubuntu on it with current linux-dvb-cvs.

The results are still the same as earlier. Loading saa7146 with
saa7146_debug=99 i get lots of these in my dmesg:

[4301981.740000] saa7146: saa7146_wait_for_debi_done(): 
    timed out while waiting for transfer completion
[4301982.092000] saa7146: saa7146_wait_for_debi_done(): 
    timed out while waiting for transfer completion

Maybe that rings a bell with someone.

I'm not yet ready to give up and move on on this yet. The thing does
work under windows and people have reported that it's working for them
under linux too - all I'm missing is a report that it's actually working
for someone with a recent kernel.

I'm thankful for any hint on what to try next ...
