Bug Description

The system fan used to come on and run continually if the computer was booted when warm on 12.04. A recent update now prevents the fan from running at all, even when the machine is booted warm, and the system overheats and shuts down.

The overheating will prevent the computer from using Ubuntu.

The previous behavior on 12.04 was annoying but acceptable, since the computer could be used when rebooted when warm, which would allow the fan to run.

Update: a new update has apparently returned the fan behavior to continuous running if the computer is rebooted when the temp sensor is hot. While far from ideal, this allows the computer to be usable.

In eeepc 1001ha I have this problem with 12.04. Before the upgrade to 12.04 all was fine. Now the computer warms until it reaches 88 F and shutdown. Please, solve this problem. How can I fix it temporally?

Thanks,
Xan.

It only happens with battery.
If I leave battery, all is fine.

Confirmed: if I leave battery, the bug is not present. Although I have a "burning" cpu, when I leave battery and I plug laptop to DC, all is fine.

Battery only or Battery with plug to DC "causes" a bug.

Anyone could confirm this with other models?

Can I attach some file for triagging this bug?

Thanks,
Xan.

PS: It's an annoying bug.

I regret from above: today I have a reboot **without** battery. So the problem is present always, with and without battery.

Thanks,
Xan.

Anything I could do for triaging this bug?

Thanks,

Xan, the behavior quickly reverted, so now if I reboot when the temperature
is elevated, the fan will come on and run continually. I monitor the temp,
and can control the processor speed with this program:

eee-control-tray is a utility for controlling Eee PC hardware, hotkeys and
more through eee-control-daemon.

Netbook Model: ASUSTeK Computer INC. AUTODETECT
eee-control-daemon version: 0.9.6
which can be found at:
http://launchpad.net/eee-control/

I don't know how else to assist. I think that there are developers that
are aware of this problem.

I hope this helps.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in linux (kernel).

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://help.ubuntu.com/community/ReportingBugs.

N. Bruce Nelson, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
