Increased Power, Load and Temperature in Linux 3.4.X

I used to get NMI watchdog error but no more. You could get rid of mei error by blacklist mei.

Hey graysky, the link is down. Could you please reinstatement the link for another day or two? It looks like I will have to stay on 3.8 for some time.

Is there a pre-3.4-post-aspm/power-regression/-stable-kernel that will support modules like thinkpad_acpi, tp_smapi, bbswitch, etc. I tried linux-lts (3.0) which is too old and wouldn't let me compile these modules.

Has anyone noticed bigger power consumption (reduced battery time)/temperatures on laptops (preferably with i915 gpu) with kernel > 3.7.3 ? Is it only my idea?

Yes, it seems to be related.

There is an issue with 3.4 kernel. I have the same issue.

Back to 3.3.7 for me.

I will try a git-bisect on my free time.

??? what's the point in posting the same thing over and over again?

firewalker · 2012-06-22 10:13:10

Maybe related with this?

Did someone opened an upstream bug report?

I can confirm this bug, and not restricted to Intel.

AMD Phenom II 965BE

Following a (as I thought) unrelated thread regarding load monitoring in general, this thread was brought to my attention. The only none 3.4 kernels in AUR are ice and fedora. ice is 3.2, and fedora is 3.3. I elected to install ice, booted and average load (queueing) has dropped by 33%, temps have dropped 9C compared with 3.4. I can also confirm that it's a 3.4 kernel issue, and not ck specifically (I personally prefer the ck kernels - may I have a 3.2/3.3 binary). I'll keep my eye on things with the 3.2 ice kernel for the next 24 hours, but honestly 24 minutes tells me enough.

donniezazen · 2012-07-03 23:32:33

@Roken I have had same observations. I have previously edited the OP to reflect that it's not a ck problem.

@donniezazen I have a T420s which has very similar hardware compared to your machine (i7 2620, 8GB RAM, Intel 3000, NVIDIA Optimus 1GB). Which kernel do you have currently installed, what powersaving masures have you taken so far and how long does your battery last? (I assume your run a 6-Cell battery?)

debdj · 2012-07-04 16:27:39

I updated to 3.4.4-2-ARCH and I havn't noticed anything so far.
Athlon X2 240.
I use the powernow-k8 driver with the ondemand cpu governor to scale cpu freq.
It generally stays @ 800MHz and the temp is alright ~ 43 deg. cel.
At higher load(75-100%) when its clocked to the max(2.8G), it generally stays @65-85 deg. cel.
But thats normal for my system from what I've seen.

@delexi Basically, bug started around late 3.3 or early 3.4. So, anything before that is good. I have not looked into 'how to compile kernel' so that I can get 3.3. I am instead using linux-ice which is 3.2. Optimus won't work with it. Other than that it's a solid kernel.

Here is my kernel line and rc.conf module and daemon line. I use no other modifications.

kernel /vmlinuz-linux-ice root=/dev/sda5 ro i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 drm.vblankoffdelay=1

MODULES=(thinkpad_acpi tp_smapi)

DAEMONS=(hwclock syslog-ng dbus networkmanager netfs crond @adb @avahi-daemon @cupsd @bumblebeed @sshd @ntpd @alsa @acpid @sensors @hddtemp @thinkfan @laptop-mode lightdm)

Open a terminal and run:

uptime

Have a look at the three numbers at the end. If they are more than 1.0 then you may have the problem and just not know it. You would usually expect the first to be < 0.2 on an idle system.

debdj · 2012-07-05 13:22:57

@roken

You're right. I seem to have the problem too. A bit strange though.
When I have firefox and some terms open it's ~ 0.79 - 0.87. With completely idle it goes above 1.

EDIT: the man page of uptime and http://en.wikipedia.org/wiki/Load_%28computing%29 provides some insight on load avarage .
The above numbers were when my system was running @800MHz
With the same apps running it dropped to 0.37 - 0.48 (for the last minute) @2.8GHz
Still its a bit higher than usual.

I had the same problem. I've find out on my laptop that problem occurs only on AC. After disconnecting AC temperature immediately goes down. I've also found that bfq scheduler was to blame. After switching to cfq problem disappears.

@b00rt00s When you say you switched to cfg, do you mean you were using linux-ck and changed scheduler to cfq or you went to stock kernel? Because it seems problem is upstream and not in bfq.

b00rt00s · 2012-07-31 20:44:55

@donniezazen After longer observation It looks like the same happens on cfq and bfq. Also my problems where caused by linux-ck. On [core] kernel I don't see any difference between 3.4.7 kernel and 3.0.38. But after looking at the first post in the thread I see You are also using linux-ck. Maybe the patchset is the problem?

unknwn · 2012-08-18 15:25:11

My laptop uses ~3W more with linux-ck over linux package. Powertop reports that audio codec is always active(100% usage) with -ck and shows estimated audio codec power usage ~2watts yet i can't force it to suspend. With linux audio codec is suspended when not used.

donniezazen · 2012-08-18 22:14:50

I am using linux-lts. It's giving me superb temp and power usage. My system temperature is now 50C and power usage is between 9-10W.
