Comment 34 for bug 2026658

I have been able to get thermald log info for bug 2.
(This was accomplished with locked power details, so the computer remained usable over the ~30 hours of uptime before I saw it had triggered.)

The log file itself is over 50MB, I've zipped it into a 3.8MB file.

Grep output to confirm bug 2:
/sys/devices/system/cpu/intel_pstate/hwp_dynamic_boost:0
/sys/devices/system/cpu/intel_pstate/max_perf_pct:70
/sys/devices/system/cpu/intel_pstate/min_perf_pct:10
/sys/devices/system/cpu/intel_pstate/no_turbo:1
/sys/devices/system/cpu/intel_pstate/status:active

To save a lot of bother, from my own system logging script I determined that bug 2 was triggered between (2023-08-14) 21:37:13 and 21:37:14 (US Eastern). Converting that first one to unix timestamps yields 1692063433.

So, of these 3 logging events, 2 shoouuld be the before/after log statements from thermald - unless I've screwed up my math:

and also that ls statement:
$ sudo ls /sys/bus/acpi/devices/INTC1041:00/
hid modalias path physical_node power status subsystem uevent uid wakeup

I'm now going to attempt to trigger the bug using that older kernel version, since I know how to reliably manually trigger it using `stress`.
