TechniSat SkyStar S2
The CX24118A Tuner supports QPSK, 8PSK Modulation.
Driver now in the main media tree, should be included in 4.2 kernel. Can be installed before then with the V4L-DVB media_build process: How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers. Requires firmware file dvb-fe-cx24120-18.104.22.168.fw.
High bandwidth transponders (>45Mbps) are problematic, eg 23.5E 12207 V 27500 5/6.
Page Allocation Failure
Some systems see occasional page allocation problems on module reload/init (even on systems with 1GB of ram). The following command may help:
echo 16384 > /proc/sys/vm/min_free_kbytes
