Yes, if your kernel is not updated to include the patches which make the amd_pstate_epp as the default mode, you would need to add amd_pstate=3Dacti= ve commandline. After you added the amd_pstate=3Dactive and boot system up, we can check wh= y the EPP values cannot be changed.=20 Perry. --=20 You may reply to this email to add a comment.
