I'm having some thermal trouble since I've started using kernel >4.0.x with my new laptop. According to psensor and sensord, CPU temperature jumps above the 90C, stays there for around 1second, and goes back to 50C. All transitions happen in around 100ms. I've cleaned and re-applied thermal paste and checked the connections twice. More interestingly, this doesn't happen when the CPU is under heavy-load, but when it is waiting idly. Sometimes sensord reports the CPU temp has gone over the critical threshold of the CPU and device shuts down itself immediately.
There is also Windows 10 installed as a dual boot and didn't see this problem on it when idle or under heavy load.
Dmesg output is full of following warnings;
[ 1282.296247] CPU0: Core temperature above threshold, cpu clock throttled (total events = 109)[ 1282.296267] CPU4: Core temperature above threshold, cpu clock throttled (total events = 109)

Because of wrong temperature reporting, kernel throttles the CPU and reduces overall performance, which results in frustrating user experience.
I've tried followings and find a temporary solution;
- intel_pstate enabled, turbo-boost enabled > problem exists
- intel_pstate enabled, turbo-boost disabled > problem frequency reduced
- intel_pstate disabled, governor set to anythig other than powersave > problem exists
- intel_pstate disabled, governor set to powersave > problem frequency reduced
I'm suspicious about a kernel bug such as;
- https://bugzilla.redhat.com/show_bug.cgi?id=924570
- https://bugzilla.redhat.com/show_bug.cgi?id=1317190 |
