Title:
Dell XPS 15 9570 - Thermal Shutdown Event & Annoying Full-Speed Fan
Spin Up
Status in thermald package in Ubuntu:
Incomplete
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.
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.
