Booted normal. I cleared KA stored settings.
Now:
CPU - No changing. Default in interactive.
Hotplug - No changing. Default in mako-hotplug. No other hotplugs.
-- Before the kernel becomes stable, I think there's no need to add more features. You could also do major work in SINAI-N4.
-- once booted into launch, KA show Max frequency 1240MHz, after a few minutes it restored to 1512MHz, normal. 4 cores actived.
--dt2w - worked.
-- Thermal - it's simple, I like it~
--IO scheduler - I changed it to noop. Others no changing.
--Anything else no changing.
--Camera OK, 1080P video recording OK.
Today I will keep monitoring the logcat file to PC.
Thanks for your great work! BTW, you did so fast.

You writes to me to not modify governors/scheds

And I didn't touched it, mako hotplug is default in Quanta, I merged only optimizations, sdcardfs and other

I don't touch hotplug driver because it may cause music lags.

I add zen and other schedulers

What governors do you want to see?

By now, no reboot. And I have to join a meeting now... Governors are not so much important to me. We can see how nice the kernel will be.

I personally would like to bfq added, if it hadn't already.
And what is the current battery life on Quanta-Reborn?

A first random reboot, but it's still more stable than the other kernel.
I was in charging and playing coc.

Charging and playing may cause overhead
