@Colin I am using an ASUS Z170M-Plus MB (https://www.asus.com/sg/Motherboards/Z170M-PLUS/specifications/). It's UEFI is equip to perform active thermal management of the CPU and a few other locations on the MB. Is there a reason why the devices of TRT and ART are not detected? Are these tables required to monitor and control temperatures on my CPU and MB?
I observed my syslog also has two kernal complains on ACPI error : May 19 08:17:42 Eliot kernel: [ 0.016207] ACPI Error: [\_SB_.PCI0.XHC_.RHUB.HS11] Namespace lookup failure, AE_NOT_FOUND (20150930/dswload-210) May 19 08:17:42 Eliot kernel: [ 0.021413] ACPI Error: 1 table load failures, 7 successful (20150930/tbxfload-214) Do you think this is why /dev/acpi_thermal_rel are not created? I did not observed the "sysfs write failed trip_point_0_temp" repeating in the syslog. $ cat /var/log/syslog | grep thermald May 19 08:17:42 Eliot thermald[1086]: 22 CPUID levels; family:model:stepping 0x6:5e:3 (6:94:3) May 19 08:17:42 Eliot thermald[1086]: Polling mode is enabled: 4 May 19 08:17:42 Eliot thermald[1086]: failed to open /dev/acpi_thermal_rel May 19 08:17:42 Eliot thermald[1086]: failed to open /dev/acpi_thermal_rel May 19 08:17:42 Eliot thermald[1086]: TRT/ART read failed May 19 08:17:42 Eliot thermald[1086]: sysfs read failed constraint_0_max_power_uw May 19 08:17:42 Eliot thermald[1086]: sysfs write failed trip_point_0_temp May 19 08:17:42 Eliot thermald[1086]: sysfs write failed trip_point_0_temp May 19 09:06:05 Eliot thermald[3898]: Couldn't get lock file 3898 May 19 09:06:05 Eliot thermald[3898]: An instance of thermald is already running, exiting ... Other questions: 1. How do I verify that thermald is actually correctly managing the thermal state of my CPU and MB? 2. Does thermald overwrite the EUFI thermal management control? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1582982 Title: thermald 1.5-2ubuntu1 failures in ubuntu16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1582982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
