I have done some more testing and I have come to some more conclusions that
might be helpful.

After 2-3 days of continues running szap-s2 on different channels 
without problems I started Mythtv and scheduled a recording.
The next day the error had appeared again and I get a lot of "Slave RACK 
Fail !". I power off the computer and starts it again.
Now I run scan-s2 with parameter "-a 0 -l UNIVERSAL -s 0 -n" for a 
complete network scan. When I check the computer again in
about an hour scan-s2 hangs and once again a lot of "Slave RACK Fail !" 
messages in dmesg.
As far as I can see it appears when scanning it goes wrong and I'm not 
sure but mythtv might do some scanning in the background?

Which S2API development branch for mantis is the best to use?
