[Kernel-packages] [Bug 1781924] Re: Kernel wrong temperature reporting
1) Yup, system not hangs up, but I feel the system response slower when it happens. E.g. keyboard mouse not work for seconds. I can check if the cpufreq be changed next time I get machine. 2) Not saw the over temperature by command sensors. Isn't it reported from sysfs? If not, I can check it next time I get machine.

[Kernel-packages] [Bug 1781924] Re: Kernel wrong temperature reporting
This bug has been reported a few times in Ask Ubuntu. Just today (July 3rd, 2019) I was going back through `dmesg` and by chance I noticed on June 22nd, 2019 the errors appear about a dozen times. I've been on the same kernel version 4.14.114 LTS for a couple/few months now but I did flirt with version 4.14.120 LTS briefly and it is possible I was using that kernel version that day. I would have to check journalctl to find out for sure if someone deems it relevant. I don't view this bogus throttling error as a problem more of a curiosity if anything. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1781924 Title: Kernel wrong temperature reporting Status in linux package in Ubuntu: Expired Bug description: I'm having some thermal trouble since I've started using kernel >4.0.x with my new laptop.

[Kernel-packages] [Bug 1781924] Re: Kernel wrong temperature reporting
As I remember, I didn't have that problem in Ubuntu 16.04 but don't remember which kernel it was. I was updating the OS whenever there are new updates, so most probably I've used numbers of different kernel versions. This device is my daily laptop and it's not possible to install and test Ubuntu 16.04. But I'm a frequent dmesg checker person and I'm sure I didn't notice that kind of thermal throttling issues on 16.04. If you can suggest a way to find and test the kernels in 16.04, I'll gladly do it.

[Kernel-packages] [Bug 1781924] Re: Kernel wrong temperature reporting
I tried with 4.17 and 4.18-rcx kernels and problem still persist. Also suspend mode is not working correctly and consuming huge battery in suspend mode. If I put the device into suspend mode without setting CPU governor to "powersave", CPU burns like hell when suspended. ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1781924 Title: Kernel wrong temperature reporting Status in linux package in Ubuntu: Incomplete Bug description: 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.
