This changelog is useless as long as you do not explain in which whay that
permits power state and battery life diagnosis.

I really have a hard time to figure out why you need to print RTC time on
oops or any of the other actions. That whole thing looks pretty
overengineered for a dubious value.

What kind of information is the current stuff missing and how are you using
this new information for better diagnosis?

Thanks,
