Public bug reported: Main Problems:
- Incorrect performance throttling results in Thermal Shutdown Event (~100C on CPU) as reported in BIOS log - System fan during system idle powers at full speed for 1 second every minute or so (could also be GPU fan) Environment: Dell BIOS: 1.3.0 (Also present in 1.2.0, 1.1.3) CPU: Intel(R) Core(TM) i9-8950HK CPU @ 2.90GHz Operating Systems: Ubuntu 18.04.1 LTS Thermald Version: 1.7 Ubuntu Thermald Package: 1.7.0-5ubuntu1 Kernel: 4.17.14-041714-generic (Also present with 4.15.0-29, 4.15.0-30, 4.17.11-041711) Intel Microcode: 3.20180425.1~ubuntu0.18.04.2 Nvidia Driver: 396.51-0ubuntu0~gpu18.04.1 TLP Package: 1.1-2ubuntu1 I've documented this issue on the thermald Github page with thermald debug logs and configuration: https://github.com/intel/thermal_daemon/issues/161 Basically, I've attempted to set the temperature for B0D4 to as low as 85000 and while the debug log seems to indicate the trip has be made, the CPU scailing isn't working to keep the CPU from thermal shutdown. Disabling Turbo Boost prevents shutdown of the system. I'd expect thermald to performance throttle the CPU correctly to prevent it from a thermal overheat event. ** Affects: thermald (Ubuntu) Importance: Undecided Status: New -- 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/1786575 Title: Dell XPS 15 9570 - Thermal Shutdown Event & Annoying Full-Speed Fan Spin Up Status in thermald package in Ubuntu: New Bug description: Main Problems: - Incorrect performance throttling results in Thermal Shutdown Event (~100C on CPU) as reported in BIOS log - System fan during system idle powers at full speed for 1 second every minute or so (could also be GPU fan) Environment: Dell BIOS: 1.3.0 (Also present in 1.2.0, 1.1.3) CPU: Intel(R) Core(TM) i9-8950HK CPU @ 2.90GHz Operating Systems: Ubuntu 18.04.1 LTS Thermald Version: 1.7 Ubuntu Thermald Package: 1.7.0-5ubuntu1 Kernel: 4.17.14-041714-generic (Also present with 4.15.0-29, 4.15.0-30, 4.17.11-041711) Intel Microcode: 3.20180425.1~ubuntu0.18.04.2 Nvidia Driver: 396.51-0ubuntu0~gpu18.04.1 TLP Package: 1.1-2ubuntu1 I've documented this issue on the thermald Github page with thermald debug logs and configuration: https://github.com/intel/thermal_daemon/issues/161 Basically, I've attempted to set the temperature for B0D4 to as low as 85000 and while the debug log seems to indicate the trip has be made, the CPU scailing isn't working to keep the CPU from thermal shutdown.
