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: [1692063430][DEBUG]poll exit 0 polls_fd event 0 0 [1692063430][DEBUG] energy 1:524286656:772647335 mj: 7965 mw [1692063430][DEBUG]read_temperature sensor ID 4 [1692063430][DEBUG]Sensor TCPU :temp 48000 [1692063430][DEBUG]pref 0 type 4 temp 48000 trip 103050 [1692063430][DEBUG]pref 0 type 4 temp 48000 trip 104550 [1692063430][DEBUG]pref 0 type 4 temp 48000 trip 106050 [1692063430][DEBUG]pref 0 type 4 temp 48000 trip 107050 [1692063430][DEBUG]pref 0 type 4 temp 48000 trip 109050 [1692063430][DEBUG]pref 0 type 0 temp 48000 trip 110050 [1692063430][DEBUG]pref 0 type 2 temp 48000 trip 110050 [1692063430][DEBUG]Passive Trip point applicable [1692063430][DEBUG]Trip point applicable < 1:110050 [1692063430][DEBUG]cdev size for this trippoint 0 [1692063430][DEBUG]pref 0 type 3 temp 48000 trip 90000 [1692063430][DEBUG]Passive Trip point applicable [1692063430][DEBUG]Trip point applicable < 2:90000 [1692063430][DEBUG]cdev size for this trippoint 4 [1692063430][DEBUG]cdev at index 13:Processor [1692063430][DEBUG]>>thd_cdev_set_state temperature 90000:48000 index:13 state:0 :zone:4 trip_id:2 target_state_valid:0 target_value :0 force:0 min_state:0 max_state:0 [1692063430][DEBUG]zone_trip_limits.size() 0 [1692063430][DEBUG]def_max_state:0 temp_max_state:0 curr_max_state:0 [1692063430][DEBUG]thd_cdev_set_13:curr state -1657 max state 0 [1692063430][DEBUG]def_min_state:0 curr_min_state:0 [1692063430][INFO]op->device:Processor -1658 [1692063430][DEBUG]set cdev state index 13 state -1658 [1692063430][INFO]sysfs write failed /sys/class/thermal/cooling_device13/cur_state [1692063430][INFO]Set : threshold:90000, temperature:48000, cdev:13(Processor), curr_state:-1658, max_state:0 [1692063430][DEBUG]< 2:90000 [1692063434][DEBUG]cdev size for this trippoint 4 [1692063434][DEBUG]cdev at index 27:rapl_controller [1692063434][DEBUG]Need to switch to next cdev target 0 [1692063434][DEBUG]cdev at index 28:intel_pstate [1692063434][DEBUG]>>thd_cdev_set_state temperature 90000:90000 index:28 state:1 :zone:4 trip_id:2 target_state_valid:0 target_value :0 force:0 min_state:0 max_state:0 [1692063434][DEBUG]def_min_state:0 curr_min_state:0 [1692063434][DEBUG]thd_cdev_set_28:curr state 1 max state 10 [1692063434][INFO]cdev index:28 consecutive call, increment exponentially state 3 (min 0 max 10) (1:1) [1692063434][DEBUG]def_max_state:10 temp_max_state:0 curr_max_state:10 [1692063434][DEBUG]op->device:intel_pstate 3 [1692063434][DEBUG]set cdev state index 28 state 3 percent 70 [1692063434][INFO]turbo disabled [1692063434][INFO]Set : threshold:90000, temperature:90000, cdev:28(intel_pstate), curr_state:3, max_state:10 [1692063434][DEBUG]<>thd_cdev_set_state temperature 90000:49000 index:13 state:0 :zone:4 trip_id:2 target_state_valid:0 target_value :0 force:0 min_state:0 max_state:0 [1692063438][DEBUG]zone_trip_limits.size() 0 [1692063438][DEBUG]def_max_state:0 temp_max_state:0 curr_max_state:0 [1692063438][DEBUG]thd_cdev_set_13:curr state -1658 max state 0 [1692063438][DEBUG]def_min_state:0 curr_min_state:0 [1692063438][INFO]op->device:Processor -1659 [1692063438][DEBUG]set cdev state index 13 state -1659 [1692063438][INFO]sysfs write failed /sys/class/thermal/cooling_device13/cur_state [1692063438][INFO]Set : threshold:90000, temperature:49000, cdev:13(Processor), curr_state:-1659, max_state:0 [1692063438][DEBUG]<
