Bug Description

Hello,

Since updating to linux 3.8-rc3 my CPU is clearly overheating compared to linux 3.7.
I clearly feel that the laptop is warmer and there's more fan noise with 3.8-rc3.

Here is some average temps for both kernels :

kernel Idle Busy (VLC playing, Chromium open with several tabs)
3.7 46°C 51°C
3.8-rc3 54° 61°C
Diff +8°C +10°C

There is no problem with CPU load, in both case it stay around the same percentage.

NB: I wanted to use ubuntu-bug to report this bug but for some reason it thinks my linux kernel comes from mainline when it comes from the ubuntu repositories. So, if I need to complete this bug report with logs, please inform me.

John

Does this issue go away if you boot back into the v3.7 kernel?

Also, can you test the v3.8-rc1 kernel to see if it also has the bug:

Yes the issue goes away with 3.7 kernel, i'll try with 3.8-rc1.

Thanks, John. We should be able to bisect this issue since it goes away in v3.7. We just need to identify the first kernel version that introduces the bug. if v3.8-rc1 is good, we should next test v3.8-rc2. If v3.8-rc1 is bad, we can bisect between v3.7 and v3.8-rc1.

Thanks for testing!

I tried : 3.7, 3.8-rc1, 3.8-rc2 3.8-rc3 and the problem is present with 3.8-rc1, 3.8-rc2 and 3.8-rc3.

It's crazy cold here so the overheating is lower than when I detected it last week but I still got a +5°C (idle) with 3.8-rc1, 3.8-rc2 and 3.8-rc3.

Can you also test the upstream v3.7 final kernel? It can be downloaded from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/

So I tried the 3.7 final kernel and also 3.7.1 and 3.7.2, no overheating for these three.

So what's the next step ? I read the wiki page on Bisecting, and for what I understood I should git clone ubuntu-raring.git and start there. Am I correct ?

I started a kernel bisect between v3.7 final and v3.8-rc1. The kernel bisect will require testing of about 7-10 test kernels.

I built the first test kernel, up to the following commit:
6be35c700f742e911ecedd07fcc43d4439922334

The test kernel can be downloaded from:
http://people.canonical.com/~jsalisbury/lp1098874

Can you test that kernel and report back if it has the bug or not. I will build the next test kernel based on your test results.

I can bisect on my end and build the test kernels for you, unless you prefer to do it on your end?

I tried to do it on my own but I didn't managed to build the kernel, so I would be great if you could do it. I'll try the first one and get back to you.

I get after reboot with no application running :

Also, would it be possible for you to run top or powertop when this bug happens? It would be good to know if there is a process consuming a considerable amount of CPU.

Hi John,

Can you test the latest v3.8-rc6 kernel, which can be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc6-raring/

Also, do you happen to know if this happens with the nouveau driver? That would be a good test.

Hi,

I've tried the 3.8-rc6 kernel and it seems that the overheating problem is gone !

My laptop have the Optimus hybrid graphics system, I have to use bumblebee in order to enable the Nvidia card, and I think it's not compatible with the Nouveau driver.

@John, that's great news that the issue is gone in 3.8-rc6. Can you apply the latest updates, so you are running the 3.8.0-4.8 kernel? Then confirm where or not this bug is resolved?

Hi, so the bug is definitely gone with the 3.8.0-4.8.

Thanks a lot for having taken the time to investigate it.
