            Bug ID: 204893
           Summary: Package temperature above threshold, cpu clock
                    throttled
           Product: ACPI
           Version: 2.5
    Kernel Version: 5.0.0-27
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW

          Priority: P1
         Component: Power-Thermal
          Assignee: acpi_power-ther...@kernel-bugs.osdl.org
          Reporter: ser...@iskynet.es
        Regression: No

I have a MSI GS75 notebook running on Ubuntu 18.04 and sometimes I see errors
related to CPU frequency scaling like below:
