Hello Kai-Heng, or anyone else affected, Accepted thermald into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/thermald/1.7.0-5ubuntu2 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to thermald in Ubuntu. https://bugs.launchpad.net/bugs/1803360 Title: Fanless systems with DPTF shutdown before using any passive cooling device Status in thermald package in Ubuntu: Fix Released Status in thermald source package in Xenial: Won't Fix Status in thermald source package in Bionic: Fix Committed Status in thermald source package in Cosmic: Fix Committed Status in thermald source package in Disco: Fix Released Bug description: == SRU Justification, Cosmic, Bionic, Xenial == There are some new fanless platforms use DPTF's virtual sensor instead of INT340X devices. Because of that, the _PSV is no longer in use, at least not directly, hence its value may set higher then _CRT. To a fanless system that means no cooling device gets activated before _CRT, so the system will be considered overheated by Linux kernel, and gets shutdown by the kernel. == Fix == Upstream fix https://github.com/intel/thermal_daemon/commit/97976782dd26b4d592ccb97eb89c2a3a871a22a9 == Testing == Exercise CPUs on a fanless INT340X device with _CRT ACPI objects and try and reach the trip point. Without the fix thermal overrun occurs and this trips CPU shutdown. With the fix, thermald will start to throttle the system and get it out of the thermal overrun zone. == Regression Potential == This modifies the behavior for just INT340X devices with ACPI _CRT objects, specifically, now to honor this setting. This is a small subset of devices with these objects and the change will in face make thermald catch systems before they hit thermal overrun, so the risk of regression is small. This fix also has been reviewed by the thermal experts at Intel, so it seems like a very reasonable workaround for these specific use cases.
