I assumed you were building it in since you were > messing with CONFIG_EXTRA_FIRMWARE. I have learnt something new today, CONFIG_EXTRA_FIRMWARE is not needed for modules. I tried RADEON_DPM_FORCED_LEVEL_LOW and RADEON_DPM_FORCED_LEVEL_HIGH, but they didn't work either. Then I commented out: ni_dpm_force_performance_level(rdev, RADEON_DPM_FORCED_LEVEL_AUTO); With that I can boot the system and dpm seems to work, because the fan is nice and quiet. Also cat /sys/kernel/debug/dri/64/radeon_pm_info says this: uvd vclk: 0 dclk: 0 power level 0 sclk: 25000 mclk: 15000 vddc: 900 vddci: 950 Then (with RADEON_DPM_FORCED_LEVEL_AUTO enabled again) I commented out: if (ni_send_msg_to_smc_with_parameter(rdev, PPSMC_MSG_SetForcedLevels, 0) != PPSMC_Result_OK) That resulted in screen corruption but it worked when I instead commented out: if (ni_send_msg_to_smc_with_parameter(rdev, PPSMC_MSG_SetEnabledLevels, 0) != PPSMC_Result_OK)
