I think i've got a problem with the intel driver: Sometimes, I think especially after running graphics intense applications, RC6 is disabled completely and heats up my Thinkpad X220t to 90 degree celsius, while idling. At first I thought that this is a CPU frequency scaling issue, as the cpufreq_powersave claims to be running at 800 MHz, but i7z (http://code.google.com/p/i7z/) shows all multipliers to be 25 -> 2.5 GHz CPU clock. Powertop 2.1 reveals that the GPU is 100% active, 0% RC6, 0% RC6p and 0% RC6pp, and the CPU is 99,9% in C7-deep-sleep, at maximum frequency. /sys/kernel/debug/dri/0/i915_ring_freq_table also pointed the issue to being caused by the GPU. intel_gpu_top shows a total idle. I'm on ArchLinux, Kernel 3.6.2, xf86-video-intel-git b42d81b63f5b6a571faffaadd42c74adce40128a, this is 2.20.10. Problem first occured with Kernel 3.6.0. Core i5-2520M HD 3000 >cat /proc/cmdline >cryptdevice=3D/dev/sda2:cryptroot root=3D/dev/mapper/cryptroot ro vga=3D= 791 >i915.i915_enable_rc6=3D7 i915.modeset=3D1 i915.lvds_downclock=3D1 >i915.semaphores=3D1 drm.vblankoffdelay=3D1 init=3D/bin/systemd >initrd=3D../initramfs-linux.img BOOT_IMAGE=3D../vmlinuz-linux Sometimes it can be fixed by going to pm-suspend and waking up. A reboot always fixes it, until it randomly locks up the GPU again. Please help me how i can do further investigation to catch the bug. As this makes my Laptop consume ~40W, it would be really nice if this gets fixed.
