3.3.5+ power regression still present
This thread shall hunt down the power regression bug first mentioned here:
https://bugs.archlinux.org/task/29850
The load average bug has been fixed, but power usage is still ~double than 3.3.4.
As the doubled power usage really is annoying, maybe we can track back the origin somehow.
The origin may be in the kernel (https://lwn.net/Articles/496154/) or at a complete different location we haven't thought of yet.
To discover whether this is hardware related, we should first collect and compare specs of affected and non-affected laptops.
Please report your status in the following form:
Affected?, Laptop brand, CPU-vendor, CPU-name, GPU-name (+kernel driver), chipset, current kernel versionPower usage statistics (wattage before -> after) would also be nice.
Ask friends/etc if they have the same issues, and share this please.
Enough attention is necessary to get this fixed!

Re: 3.3.5+ power regression still present
I thought to give stock kernel a try, heck I am running nothing out of ordinary. My temp is over 70C and power is 24W.
I had this problem before running arch on a Lenovo Thinkpad T420. After a fresh install of arch one month ago, I had a battery life of round about 8 hours. I achieved this with the tweaks mentioned here: https://wiki.archlinux.org/index.php/Le … _arguments After upgrading the kernel I had a quite higher power consumption of up to 24W -- I think before it must have been between 10W and 15W. I'm not very sure about the exact value.
Since then I tried to tweak battery life with powerdown ( https://aur.archlinux.org/packages.php?ID=57421 ) by taylorchu. This helped a bit.
Now, I just figured out that adding
drm.vblankoffdelay = 1as described under https://wiki.ubuntu.com/Kernel/PowerMan … vingTweaks really helped a lot and reduced the power consumption of 17W I had one hour before to 9W - 12W.
So this is my configuration:
niklaas@len-t420 ~ % grep i915 /boot/grub/menu.lst
kernel /vmlinuz-linux root=/dev/mapper/arch-root cryptdevice=/dev/sda5:luks ro i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 drm.vblankoffdelay=1 resume=/dev/mapper/arch-root resume_offset=40960niklaas@len-t420 ~ % sudo powernow

Maybe this helps a bit.

Re: 3.3.5+ power regression still present
@niklaas I do use boot kernel parameters. I have not tried powerdown. I will give it a try. What DE/WM do you use? Power consumption tends to be high on DEs then simple WMs. Does powerdown interferes with powertop and laptop-mode-tool?
UPDATE:- linux-lts has brought down my system temperature and power usage to less than 50C and 9-10W respectively. It's working great.

I'm using Xfce. Not with powertop but I think with laptop-mode-tools.
You could also try domac's scripts for pm-utils (git: https://github.com/domac/archlinux/tree … pm/power.d).
