If you read the entire thread it was MartinG that had the problem with
"Slave RACK Fail". My machine just completely locked up before I removed
the logging in open-sasc-ng. I'm currently using a vanilla 2.6.30.5
kernel, with open-sasc-ng r77 and s2-liplianin-16e3dc6f2758, on a Debian
system with MythTV 0.21 from the vanilla sources.
The only thing I've had to do to get open-sasc-ng to compile was comment
out the lines containing "owner", specifically lines 175,187,196,221 in
dvbloopback/module/dvblb_proc.c

I can remember seeing Slave RACK Fail errors when using the older mantis
driver from Manu (not the mantis-v4l one). That was however only when
booting up, since it paused for a few seconds while displaying 4 of
those errors. I don't see it now with the newer drivers though.

Keep in mind that we don't even have the same card, since I have the
AD-CP400 (DVB-C version).

Thanks,
