Testing 6.0.9-060009-generic behavior

output of `uname -a`
Linux TheUssBenterprise 6.0.9-060009-generic #202211161102 SMP PREEMPT_DYNAMIC Wed Nov 16 12:14:18 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

Description of behavior:
- The throttling does occur initially after running stress -c 1 and -c 2. It sticks at 400Mhz briefly after stressing for ~2 minutes, but unlike with 6.2.0-27.28 the system recovers afterwards.
- Looking at power details, long_term_power drops to 0.125, but then very slowly recovers back up towards the default of 65.
- While stressing at high cpu temperatures /sys/devices/system/cpu/intel_pstate/max_perf_pct transiently drops down to 90, but recovers up to 100 almost immediately.
- After letting it recover for a while I attempted to get the cpu to throttle again using, but I couldn't make it happen.

thermald log attached (log updates for frequently during stress test).

I will now try to get that version of thermald compiling and test on 6.0.9 and 6.2.x
