Hi there! I've just installed Debian stable on my Cubieboard using their installer. Debian's mainline 3.16 kernel works fine but cpufreq is missing (sunxi 3.4 kernel supports it).
I've submitted a bug [0] in the Debian BTS and tried kernel 4.0 and 4.1 from unstable and experimental branches with no success (cpufreq support should be there from linux 4.0 [1]). I'm forwarding that bug here as suggested. Thanks for helping! Leonardo [0] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=793185 [1] http://linux-sunxi.org/Linux_mainlining_effort#Merged_into_4.0
