Ok, I thought your system cannot load pstate driver, not the problem is sim= ple to resolve. Have you configured the kernel config to enable the default mode 3(EPP) or = set to disabled? Could you check your kernel config if you have enabled the AMD pstate drive= r? Here is my kernel config option, you can update config if you have not enab= led it to default 3.=20 # grep -rsn AMD_PSTATE .config 693:CONFIG_X86_AMD_PSTATE=3Dy 694:CONFIG_X86_AMD_PSTATE_DEFAULT_MODE=3D3 695:# CONFIG_X86_AMD_PSTATE_UT is not set Perry. --=20 You may reply to this email to add a comment.
