This doesn't answer the two parts of my question. When stopped it working using /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor from command line and why stopped it working. Btw. unless the Ubuntu kernel configs didn't change, there's no need to load a module at all, see $ grep CPU_FREQ_GOV config-4.4.0-127-lowlatency CONFIG_CPU_FREQ_GOV_COMMON=y CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_POWERSAVE=y CONFIG_CPU_FREQ_GOV_USERSPACE=y CONFIG_CPU_FREQ_GOV_ONDEMAND=y CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
