Governors Problems

. not on servers

If your system is using the new driver called intel_pstate. There are only two governors available when using this driver: powersave and performance.

• disable the current driver: add intel_pstate=disable to your kernel boot line. Editing /etc/default/grub and adding:

GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=disable" And then updating grub.cfg ala grub-mkconfig -o /boot/grub/grub.cfg

• load the userspace module: modprobe cpufreq_userspace
• load the ondemand module: modprobe cpufreq_ondemand
