            Bug ID: 264775
           Summary: acpi_thermal: passive cooling only throttles cpu0
           Product: Base System
           Version: 13.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: crahman@gmail.com

Back when all the cpu frequencies were locked to cpu0's frequency, this worked
fine.  However, now that that is not true, reducing the frequency of cpu0 and
leaving the others at their maximum frequency has a minor affect upon
temperatures, leading to overheating and shutdowns when passive cooling is
needed.
