[Kernel-packages] [Bug 1803442] Re: Thermal and power monitoring issues: CPU overheats and fan control broken/strange
I was testing with mainline/v4.20-rc3 but it was unusable on my machine: running the Quadro P3200 with the nouveau driver created a completely broken display (the nVidia 390 drivers are fine, though). At least this behavior is is identical between 4.18.0-11 and mainline/v4.20-rc3 So unless I have a way to run mainline/v4.20-rc3 with the Ubuntu nVidia package I can't test. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- 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/1803442 Title: Thermal and power monitoring issues: CPU overheats and fan control broken/strange Status in linux package in Ubuntu: Confirmed Bug description: On my ThinkPad P72 with i7-8850H CPU (Coffee Lake) the thermal setup is horrible: it runs very hot (you can feel it on the keyboard as well as the air exhausted by the fan) even when idle, the fan speeds up and gets silent after a a short time for no obvious load reasons when the system is idle.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.20 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
