I'm missing acpi-cpufreq in your module list. Is CONFIG_X86_ACPI_CPUFREQ enabled? What CPU frequency governor is enabled (`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor`)? By the way, 58°C is not particularly hot. Of course, it depends on where it is measured. For measuring it, check that you have CONFIG_SENSORS_CORETEMP enabled. Regards, Florian Philipp
