Rainer, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
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 (not the daily folder, but the one all the way at the bottom) 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-v3.12-rc7

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:
  Laptop to hot - VID to high

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  My laptop goes to very hign temperature. First I think it was a fan
  problem. I adjusted thinkfan to use the disengaded option. Now my fan
  ist at maximim speed if the temperature goes over 67°C. But still it
  is not possible to run the laptop for a longer time an 100% CPU. It
  then overheats and stops working. For example just after clamscan
  starts working the fan is at maximum speed (5600 revolutions) and the
  tempurature goes up over 85°C, the CPU usage is the about 70%.

  My standard governer is "ondemand". By using "powersave" the temparure
  will be about 5-10°C decrease.

  My investigation show me that in my oppinum the VID is to high. To varify this i do the following:
  -  rdmsr -p0 [1] 0x0199 for every speed steps
  -  the governer "ondemand" switches the MSR 0x199 between
     - 0x0613, which means 1GHz and 1.275V? 
     - 0x081c, which means 1,33GHz and 1.3875V?
     - 0x0b28, which means 1,83GHz and 1.5375V?
  > by 100% CPU the laptop overheats and stops

  - set the governer to userspace 1.833GHz
  - reduce the VID using: wrmsr -p0 [1] 0x0199 0x0b20
  > the temparature goes not over 65°C by starting load that goes to 100% CPU!.

  I see that the VID is allways set to 0x0b28 when the governer change
  the speed to the highest speed. I don't know if the governer or an
  other kernel module set the VID The Sped (FID) is selected by the
  governer.

  The FID/VID vor maximum should be set to 0x0b20 instead 0x0B28 and
  every thing would fine.

  Here are some infos about my system:

  It is a lenovo Thinkpad R60
