Ok well this is interesting.
It has been over 24 hours (uptime 1 day 15:48hrs) and bug 2 still hasn't triggered, "Degraded = no".

I probably need this computer today, so I ran `stress -c 1` to try to force the high temperature power state after running the script to reset the power values, but with lock set to False. This went onto the ideal cpu core at 4.8ghz, package temperature spiked up to ~93 degrees C, and eventually the power parameters dropped to this:

{'backup_rest': 281474976776192,
 'locked': False,
 'long_term_enabled': True,
 'long_term_power': 0.125,
 'long_term_time': 28.0,
 'short_term_enabled': True,
 'short_term_power': 250.0,
 'short_term_time': 512.0}

Bug 2 still had not been triggered, cpu was throttled to 400Mhz, so I reset the power values again this time with lock=True. When I ran `stress -c 1` it was on the ideal core but now limited to 4.3ghz with a cpu package temp of ~67.

I ran the grep and get this:
/sys/devices/system/cpu/intel_pstate/hwp_dynamic_boost:0
/sys/devices/system/cpu/intel_pstate/max_perf_pct:90
/sys/devices/system/cpu/intel_pstate/min_perf_pct:10
