Date: Sun, 4 Mar 2012 10:52:57 GMT [thread overview]
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. :/
