Normally the system hardware needs to reinitialize CPPC and low-level power management firmware when CPPC driver loading, so it better to change grub parameters and reboot again. dynamically removing amd-pstate and load acpi_cpufreq probably cause some potential issues.=20 Perry. --=20 You may reply to this email to add a comment.
