There is no scaling_govenor file in the .../system/cpu/... tree. This kernel is 2.6.33. Whereas the other system kernel is 3.5.3. > More information on tweaking your setup: > http://wiki.linuxmusicians.com/doku.php?id=system_configuration Excellent resource. I was also going to try installing the CCRMA RT kernel and any "accessories" it might require.
