May 18 10:08:11 Eliot thermald[1012]: TRT/ART read failed
These messages above occur because the device entries do not exist on
your system, so they are just informing you that the ACPI TRT (Thermal
Relationship Table) and ART (Active Relationship Table) cannot be read
(probably because the corresponding ACPI _TRT and _ART objects do not
exist on your machine). I believe these errors should occur just once
during the lifetime of thermald and are just informing you that the
capabilities do not exist.
May 18 10:08:12 Eliot thermald[1012]: sysfs read failed
constraint_0_max_power_uw
The above error shows that the Maximum Power RAPL (Running Average Power
Limit) interface in /sys/class/powercap/intel-rapl cannot be read,
however since the failure does not occur on the
constraint_1_max_power_uw then the RAPL max power reading has probably
worked, so there is no need to worry about that message.
May 18 10:08:12 Eliot thermald[1012]: sysfs write failed trip_point_0_temp
May 18 10:08:12 Eliot thermald[1012]: sysfs write failed trip_point_0_temp
The above is of interest because the thermal zone trip point temperature
setting can't be updated, I guess this message is going to be repeated
many times.
>From your bug it is hard to determine if the messages are being repeated
many times or not. Can you run thermald for say 1hr and attach the full
log so we can see what messages are spamming the log.
