Public bug reported: I have a weeks old Lenovo T460s running Ubuntu 16.04. After seeing MCEs for due to temperature, I was advised to try the upcoming HWE-Y kernel.
I installed linux-image-4.8.0-9-generic from the canonical-kernel-team-ubuntu-unstable-xenial PPA and rebooted. When I returned to my machine in the morning I found it had hard locked up over night, it was very hot and all the fans were going at full speed. With the 4.4 kernel, I got messages like the following: Sep 17 22:45:13 malefic kernel: [213000.178417] CPU2: Core temperature above threshold, cpu clock throttled (total events = 9521) With 4.8, it increased to: Sep 20 17:14:13 malefic kernel: [24571.915198] CPU2: Core temperature above threshold, cpu clock throttled (total events = 42953) (Although there's a fair bit of variation). I also noticed that thermald was spewing a lot of error messages to syslog: http://paste.ubuntu.com/23207813/ The thermald spew went away and the number of 'temperature above threshold' events went down once I downgraded back to 4.4. ** Affects: thermald (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1625741 Title: thermald doesn't seem to work when running with HWE-Y on Ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1625741/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
