Created attachment 91222 [details] lspci -vv linux-sabayon-3.12.5 https://github.com/Sabayon/kernel I installed the lastest available kernel version on sabayon-weekly repository. sha1sum /lib/firmware/radeon/RV770_smc.bin 43e2fc7b9faa57e78401e1b1c609f71374cc8109 /lib/firmware/radeon/RV770_smc.bin Whem booted with radeon.dpm=1 as a kernel parameter on grub, screen flicks: jumps down some pixels and go to normal position every ~4 seconds very fast. Whem /sys/class/drm/card0/device/power_dpm_force_performance_level is changed to "high" or "low" flicker stops. Whem is changed back to "auto" flicker happens again, no mather what value is power_dpm_state. Whem booted without radeon.dpm=1 parameter there isn't flicker.
