started with thermald stopped:

pstate-frequency version 3.7.2
    pstate::CPU_DRIVER -> intel_pstate
    pstate::CPU_GOVERNOR -> performance
    pstate::TURBO -> 0 [ON]
    pstate::CPU_MIN -> 50% [1850000KHz]
    pstate::CPU_MAX -> 100% [3700000KHz]

start a lot of load, which sends my CPU up to crit temperature sometimes (but doesn't actually shut the machine down, so this number might be reported lower by BIOS):
stress-ng --matrix 0 -t 3m

starting thermald with log:
thermald --no-daemon --loglevel=debug > /root/thermald-debug-reduced.log 2>&1

thermald correctly reduces my performance (though it's by quite a lot) but keeps it very low even when CPU temp has been very much reduced; at this time stress-ng is still running:

stress-ng stopped for many minutes but performance still stuck on low:

at this point I stopped thermald to upload logs. I could swear I had an issue where the max freq was stuck in read-only mode and I couldn't get it back to 100% except to reboot, but I can't seem to reproduce that issue right now.
