Subject: [Bug 42858] New: thermal throttling doesn't seem to trigger on Thinkpad T420s

Message-ID: <bug-42858-12968@https.bugzilla.kernel.org/> (raw)

https://bugzilla.kernel.org/show_bug.cgi?id=42858

           Summary: thermal throttling doesn't seem to trigger on Thinkpad
                    T420s
           Product: Power Management
           Version: 2.5
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: cpufreq
        AssignedTo: cpufreq@vger.kernel.org
        ReportedBy: pierre-bugzilla@ossman.eu
        Regression: No


I have a new Thinkpad T420s and I'm noticing it getting massively hot when
putting some load on the CPU. powertop shows it spending all its time in Turbo
mode for both cores. Thermal reporting shows it hovering around 90° with the
fan on full. It hasn't been throttled even once though:

./cpu0/thermal_throttle/core_power_limit_count:0
./cpu0/thermal_throttle/core_throttle_count:0
./cpu0/thermal_throttle/package_power_limit_count:0
./cpu0/thermal_throttle/package_throttle_count:0
./cpu1/thermal_throttle/core_power_limit_count:0
./cpu1/thermal_throttle/core_throttle_count:0
./cpu1/thermal_throttle/package_power_limit_count:0
./cpu1/thermal_throttle/package_throttle_count:0
./cpu2/thermal_throttle/core_power_limit_count:0
./cpu2/thermal_throttle/core_throttle_count:0
./cpu2/thermal_throttle/package_power_limit_count:0
./cpu2/thermal_throttle/package_throttle_count:0
./cpu3/thermal_throttle/core_power_limit_count:0
./cpu3/thermal_throttle/core_throttle_count:0
./cpu3/thermal_throttle/package_power_limit_count:0
./cpu3/thermal_throttle/package_throttle_count:0

This doesn't really seem safe for the CPU or my lap. :/
