[Bug 892595] Re: Max fan speed severly limited.

 

Todd Smith, 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>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-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.

Title:
  Max fan speed severly limited.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I am running Ubuntu 11.10 on a laptop and the heat management is very
  bad.  The system will heat up and under clock to avoid damage.  When
  the system is restarted and in GRUB the fan speed will go to MAX.  The
  moment the kernel loads the fan speed drops dramatically.    Why not
  increase the fan speed to the max to try and avoid under-clocking?  In
  fact i have never seen my fan speed max out on Ubuntu!  Awful!

  Clearly this is incorrect behavior that is not only damaging but severely limits the power of the machine.
