Interesting, a new ~intermediate situation of bug 1. Its not constraining that thermal envelope quite as much now. Thermald is running, I guess bug 1 is still present but lessened since I reinstalled it? Computer was not in use.

When running `stress -c 1` it places the task on the correct ideal core (the one that clocks up to 4.8Ghz), but it bounces around between 1300mhz and 500mhz.
**update: it looks like any multiithreaded load gets shunted down to 400Mhz, but occasiional spikes on single threaded operation.

First log statement for the power envelope was at 2023-07-19T18:07:15 (roughly at boot) and then long_term_time and long_term_power suddenly step down and stay that way at roughly 3 hours 30 minutes uptime. (Current uptime is about 9 hours 50 minutes.)

here is your grep:
/sys/devices/system/cpu/intel_pstate/hwp_dynamic_boost:0
/sys/devices/system/cpu/intel_pstate/max_perf_pct:100
/sys/devices/system/cpu/intel_pstate/min_perf_pct:10
/sys/devices/system/cpu/intel_pstate/no_turbo:0
/sys/devices/system/cpu/intel_pstate/status:active

It will take a ~day for bug 2 to trigger, I will update and do the grep when that happens. If I don't need to use this computer I will leave it on without running my script to lock the power envelope at a higher value.
