I am no longer experiencing overheating since latest update 3.6.7-1?

You can downgrading system with this repo .  After downgrade i added this line to pacman.conf

IgnorePkg   = linux linux-headers linux-api-headers

now i am waiting for solution.

More you can read here

Thank you very much for the info.

I think, I'll keep my patched 3.6.6-kernel the next time. It's not perfect, but it works for me so far.

I do, too.

Booting, starting firefox and writing this post heats my (docked) Thinkpad X220 up to 69°C.

I'll stick with patched mainline for a while, I guess.

EDIT: Rebooting with mainline, starting firefox and writing this post: 48°C.

Be warned, you may need to add more packages to the ignorepkg list. If you are using packages that depend on a certain kernel version, a `pacman -Syu` will fail every time. You will also need to download these extra packages.

Good luck.

(You may also start to see a lack of features in systemd as it starts to rely on more modern kernels for certain features. This should not break systemd, just not let you use the newest and shiniest features, possibly.)

Just a note, that was something from a drm-intel branch, not the official linux-mainline branch. (My guess is it'll make it's way in sooner rather than later.)

Using 3.7.0-rc6 from Linus won't fix this yet, sadly. I've quickly looked over the commit log and nothing is popping out at me. Correct me if I'm being retarded.

You're definitely not retarded, looks like I am for not reading correctly. However, I also found out I can't reproduce the GPU issues in that report, just the symptoms only.

That's what I've noticed, as well. I've only intermittently gotten the cpu scaling issue, which could possibly be tied in, but I haven't seen anything supporting that.

This is getting quite frustrating, I really can't explain why my laptop is using ~5W more after a suspend/resume cycle. Powertop is showing my ethernet card is supposedly using more than 10W, but that looks like a bug. And as I said before, I can't reproduce the GPU issues. I have tested loads of different kernels so I'm thinking this may not be kernel related at all.

Re: Kernel 3.6.2 Power Regressions (Sandy Bridge)

curiously, it is my Ethernet adapter which seems to be using a lot of power, too. according to powertop at least. i am not even using the eth0 interface and no cable is attached, nevertheless it appears to be using more than 2W on average, only second in consumption to the LCD back light.

Well, have a look at the first few lines of powertop output on my laptop. I'm not using the eth0 interface either:

donniezazen, have a look at this bug report. See if you can reproduce some of the cpufreq artifacts in the report.

Re: Kernel 3.6.2 Power Regressions (Sandy Bridge)

I've just opened up a pacman repository with the linux-mainline packages at http://sakuscans.com/pacmanpkg/x86_64/ . Please feel free to use it. I've added in the headers and docs from the vanilla mainline package, so it may prove useful and time-saving. (If there are configuration options that don't work, tell me. I'll try to fix that nex time I release.)

This repo's linux-mainline has the msleep patch.

Thanks!

Re: Kernel 3.6.2 Power Regressions (Sandy Bridge)

I tried drm-linux-next today, and it seems to fix the issue on my X220 Tablet (I verified 2 reboots and about 20 suspends).

Here's what I did:

mkdir drm-intel-next
cd drm-intel-next/
git remote add -t drm-intel-next -f origin git://people.freedesktop.org/~danvet/drm-intel
git checkout drm-intel-next

zcat /proc/config.gz > .config
make oldconfig
make -j4

sudo cp arch/x86/boot/bzImage /boot/vmlinuz-custom
sudo make modules_install
sudo mkinitcpio -k 3.7.0-rc4-ARCH-00324-g70b12bb -g /boot/initramfs-custom.img # Kernel Version from make modules_install output

vim /boot/grub/grub.conf
reboot

Edit: removed first command, was from an aborted attempt

Please put this in a pkgbuild so people don't get random untracked files floating around their systems.

@ KaiSforza: I added your repo and tried your msleep patched kernel. I just booted up, launched KDE and just a browser and here are my temperatures:

I get similart numbers on a cold boot. I forgot to mention that it takes a suspend-resume cycle for it to all work and get normal temps/power usage.

(And thanks for trying it out.)

Also, might I ask for a powertop output if you try again, to see the cpu frequencies?

Sure. Right now I am working on stuff but I'll do it later and post the results.
Thanks for your package and repo by the way. ;-)

I tried drm-linux-next today, and it seems to fix the issue on my X220 Tablet (I verified 2 reboots and about 20 suspends).

I have bad news: Just got out of suspend and GPU was 100% active (powertop 2.1, Idle stats). That means even drm-linux-next (from yesterday) doesn't fix the issue.

Since switching to that kernel, 2 resumes out of about 4 reboots and 25 suspend-resume-cycles were bad.
