Applying this patch and removing tha 'avs' node from arch/arm64/boot/dts/marvell/armada-37xx.dtsi seems to work. Changing between governors does not freeze the board any more. I haven't checked the actual impact on the CPU speed but the values on /sys/devices/system/cpu/cpufreq/policy0/scaling_governor are correct Cheers /Ilias _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
