[Rainer <1164557@xxxxxxxxxxxxxxxxxx>]

Hello Christopher,

thanks to Your answer.

I wrote this by email, because I don't now if You immediate receive
chandes in the LaunchPad and a lot of my answers already in the
Launchpad entry.

I believe there is going some thing wrong. My laptop goes hot. I googled
a lot an try a lot. The current Radeon card driver is the open version
not the AMD. I changed what ever can reduce power.  But the Radeon is
not the problem, it only goes on top. the real problem is the CPU
(Intel) is to hot.

I can say it is the VID on the Intel CPU which is to high! Before I
switch from Windows to LINUX I had have been no problems with Windows
and LINUX. After going to newer LINUX releases the problem appears. My
investigating shows that the CPU voltage is to high, and if I set the
CPU voltage manually lower it will work without any problem. But the
governor switch always back to the high voltage at the next governor
cycle. I believe this is done by the kernel. I tryed to find where in
the source with no success.

In addition I tryed to use LINUX-PHC which would solve the problem if it
work. It did, but a lot of other problems occur by using the ubuntu-tp
kernel. so I can say LINUX-PHC would help, but it must be integrated as
standard in Ubuntu to solve all the other problems (Integration problems).

For my normal processing my bypass with the previous descripted script
(if temperature to high go to governor Powersave till the temperature is
lowered) works well. But if I must use a live Linux for backup, I must
be carefull and do not high CPU usage.

Regards Rainer

Title:
  1002:7145 [Lenovo ThinkPad R60] Laptop too hot with radeon drivers

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  My laptop goes to very high temperature. First I think it was a fan
  problem. I adjusted thinkfan to use the disengaged option. Now my fan
  is at maximum 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
  temperature goes up over 85°C, the CPU usage is the about 70%.

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

  My investigation show me that in my opinion the VID is to high. To verify 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 temperature goes not over 65°C by starting load that goes to 100% CPU!.

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

  WORKAROUND: Use the powersave CPU governor.
