Note how the CPU level doesn't show up in the 2nd case.

This is def coming from sched_mc_power_savings. Some battery script
or something is getting notified and setting this value. Can you do
a grep from / for sched_mc_power_savings ?

This still doesn't explain the flip-flop I saw just from booting,
as that was on AC the whole time.

Boot messages are def something not related to sched_mc_power_savings.
