Can you please clarify by 'always active'? /sys/kernel/debug/dri/0/i915_cur_delayinfo and /sys/kernel/debug/dri/0/i915_drpc_info would be useful, and in the extreme case a 'trace-cmd record -e i915' report. And please don't apply random hacks ' i915.lvds_downclock=1 i915.i915_enable_fbc=1 i915.i915_enable_rc6=7' without knowing the damage they may inflict upon your system.

Created attachment 68436 [details] dmesg|grep drm Since kernel v3.6, my GPU is always active. In v3.6.1 this is still the case. The software used besides (Ubuntu Quantal): xf86-video-intel: 2:2.20.9-0ubuntu2 libdrm: 2.4.39+git20120830.7080bfdf-0ubuntu0ricotz2~precise libgl1-mesa-dri: 9.0-0ubuntu1 xserver: 1.13.0 Sometimes, it helps to suspend and resume the system. It never uses any rc6-state after a fresh boot. The boot options are: pcie_aspm=force acpi_osi=Linux acpi_backlight=vendor i915.lvds_downclock=1 i915.i915_enable_fbc=1 i915.i915_enable_rc6=7 drm.debug=0x06 vt.handoff=7 Kernel v3.5 and earlier are fine.
