[Bug 572749] Re: ASUS 1001p frequency scaling

 

Rolf Leggewie, 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 kernel 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-v3.12-rc1

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:
  ASUS 1001p frequency scaling

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm running Lucid with all the latest packages on an ASUS pinetrail
  netbook 1001P.  The two CPU cores can run at 1,67GHz, 1,33GHz and
  1GHz.

  $ cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_available_frequencies
  1667000 1333000 1000000

  But even when the machine is completely idle, on the powersave
  governor and on battery, the machine will never drop below 1,33GHz.

  When the machine is on AC power something changes the governor to
  performance automatically (I certainly want to switch that off).  The
  machine then runs at 1,67GHz and the fan starts to run continuously.
  I'd rather continue to use on-demand governor and enjoy a quiet
  machine.
