Rainer, thank you for your comments. I can advise that unfortunately putting in some VID logic in augmenting the ondemand governor, or the cpufreq module in anyway like this is just simply not going to happen.
Despite this, one vital piece of information to know is are you able to utilize the proprietary drivers for your card following https://help.ubuntu.com/community/BinaryDriverHowto/ATI (strongly prefer downstream, but upstream for testing would be fine as a worst case)? ** Changed in: linux (Ubuntu) Importance: Medium => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - 1002:7145 [Lenovo ThinkPad R60] Laptop to hot - VID to high + 1002:7145 [Lenovo ThinkPad R60] Laptop too hot with radeon drivers ** Description changed: 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. - - The FID/VID vor maximum should be set to 0x0b20 instead 0x0B28 and every - thing would fine. WORKAROUND: Use the powersave CPU governor. --- ApportVersion: 2.12.6-0ubuntu1 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu 3165 F.... pulseaudio CasperVersion: 1.336ubuntu1 CurrentDmesg: [ 71.182993] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 71.185122] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 71.982542] iwl3945 0000:03:00.0: loaded firmware version 15.32.2.9 [ 72.055058] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 72.055518] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready DistroRelease: Ubuntu 14.04 LiveMediaBuild: Ubuntu 14.04 LTS "Trusty Tahr" - Alpha i386 (20131108) MachineType: LENOVO 9461DXG MarkForUpload: True Package: linux (not installed) PccardctlIdent: Socket 0: no product info available PccardctlStatus: Socket 0: no card ProcFB: 0 radeondrmfb ProcKernelCmdLine: file=/cdrom/preseed/username.seed boot=casper initrd=/casper/initrd.lz quiet splash -- maybe-ubiquity ProcVersionSignature: Ubuntu 3.12.0-2.5-generic 3.12.0 RelatedPackageVersions: linux-restricted-modules-3.12.0-2-generic N/A linux-backports-modules-3.12.0-2-generic N/A linux-firmware 1.117 Tags: trusty Uname: Linux 3.12.0-2-generic i686 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo dmi.bios.date: 08/28/2009 dmi.bios.vendor: LENOVO dmi.bios.version: 7CETD3WW (2.23 ) dmi.board.name: 9461DXG dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr7CETD3WW(2.23):bd08/28/2009:svnLENOVO:pn9461DXG:pvrThinkPadR60:rvnLENOVO:rn9461DXG:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 9461DXG dmi.product.version: ThinkPad R60 dmi.sys.vendor: LENOVO -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1164557 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.
