Thanks for detailed info. Nope, my phone is 2014817 version.
My pleasure. Not sure it's the same issue as on my device, you can check and let us know. To reproduce, just choose msm as your hotplug, disable it, enable zen decision, and go see how many cores are online. If only one, select governor again and check how many cores are online then.
On Zen decision only core is active. With MSM, all four are working.
Edit
After manually enabling, four cores are working with Zen hotplug, but don't go offline.

Not sure I understand... Make sure you have more than 15% battery. zen decision should have 4 cores online if you have more than 15% battery, and only 1 core if you have 15% or less, that's how it's supposed to be. MSM can have 1, 2, 3 or 4 cores online, depending on the situation. The bug I mentioned is that, when you change from MSM to Zen (assuming you have more than 15% battery), Zen will only have one core online. With only one core online my device gets very laggy, takes time to wake up screen, has slow reboots and errors, etc. and MAYBE that's what you were experiencing. If you then select any CPU governor, Zen will online the 4 cores as it's supposed to, and they won't go offline unless the screen is off or you have 15% battery or less. That's normal, don't worry.
I didn't touch anything related to network. Which ROM?? If it's cm13 based there shouldn't be any problem.
I'm keeping default setting close to kumajaya's kernel. Next time before enabling some other hotplug disable the previous one.

Does the kernel come with an interface for setting clock speeds, or is a third party app required?
No problem here (Vivo São Paulo). My ROM: cm13 unofficial temasek mm.

Need a little help from you guys.
Can anyone flash this new build and report if there is any issue with music player like songs stopping/freezing midway
https://drive.google.com/file/d/0B2_mFAT8KtIZWVBqbHJZS3h1N0k/view?usp=drivesdk
I don't know if this a ROM bug or a kernel bug(due to my upstream audio merges in the kernel). Please try with stock music player and a third party app like Poweramp.

I did Ashish. No issues here. Does it happen with every song or just occasionally? I'll keep trying to reproduce and report later.
Occasionally. Yesterday I was listening to songs on Poweramp v3 when I noticed this issue. BTW I'm on cm13 nightly 21/4.

OK, I'll keep testing, but I'm on snapshot 20160417 and with the latest Poweramp V2.

OK so... after more testing these are the settings that I'm more pleased with (for now), just thought I would share in case anyone wants to try:
1. Balanced:
- CPU: 200 to 1.2
- Governor: Impulse
- Hotplug: MSM, default settings
- GPU: 100 to 310
- Governor: simple_on demand
- I/O: zen, 128kb (for both internal and SD if your SD is 8 GB or less like mine)
- KSM: enabled
- TCP: Westwood
- Vibration: 50%
2. Performance/Gaming:
- CPU: 400 to 1.4
- Governor: elementalx
- GPU: 200 to 465
- Governor: msm-adreno-tz
- the rest same as above. Optionally, if you just play for a short time and want to experience the best performance, just choose both performance governors at max frequency, but the phone will heat up (and maybe explode, LOL)

Definitely not the ROM, I'm using the same one. Maybe go to the CM thread and see if people with your model are experiencing the same issue. What model do you have? Like HM20148..
Another profile guys, just in case that you are having issues with Zen decision to work reliably like I do:
3. Battery saving
- CPU: 200 to 1094
- Governor: zzmove
- CPU governor tunables: "profile" set to "zzbatp" (or set "profile_number" to "5", same thing)
- Hotplug: MSM, default settings
- GPU: 100 to 200
- Governor: powersave
- I/O: noop
- KSM: disabled
- Vibration: 0%
This is a profile that is intended to save battery to perform basic functions when you are running out, your phone WILL lag. How I use it: I set battery saver (under Android Settings>Battery) to activate at 15%, and activate this profile manually when battery saver kicks in. At the same time, I use tugabrowser (based on chromium for Qualcomm devices) and enable power save mode. Optionally, you could also enable adaptive brightness under display settings and set it to the minimum level (it will be lower than if you don't enable adaptive brightness in most of the cases).
That's it, your phone will last forever with very little battery while being able to text, call, browse, etc. normally. I also tested what happens after reboot, waking up the screen, etc. due to the issue I had with zen decision and because I saw other people worry as well. No errors or slow boot at all! Your phone will boot normally, the screen will wake up normally, etc. the only thing you'll notice it's lag during use, but bearable. Lastly, you can also do all this at any time, not just when battery saver kicks in at 15%, just select "Power save" under battery modes and battery saver mode (orange status bar) will kick in. I mention this because if, like me, sometimes you have long trips, camping, festivals, etc. and you need to make your phone last as much as you can while being able to use it, this will come in handy. Hope it helps!
Hello there, i curious about your tips for saving battery. But how to enable your profile automatically when battery reach 15%? Do you use KA feature or something? Because i have no clue about itOK, I'll keep testing, but I'm on snapshot 20160417 and with the latest Poweramp V2.

I do it manually when I need to, so I haven't given it much thought, but you can probably do it with tasker and other similar apps
I doubt it, not happening here. Try changing to MSM hotplug and see if the same happens. @Ashish94, still no sound bug with your latest nightly
Getting a new bug here, after a rebooting my device after a battery calibration from 0-100% I am unable to change the governor my ElementalX to any other.
Before switching the phone OFF at 0% I kept it at 0% but now its not changing whatever I do.
Enabled only one Hotplug ZenDecision and all other settings are same as mentioned in the OP for Balanced mode.
Using KA app from the link mentioned in the OP ( infact received the OTA update for that App this morning for build v7 and I installed it).
Even tried wiping cache and Data of the KA App.
Please look into this matter.

The Governor is now stuck on Interactive and is not changing at all.

Version Information
Status: Stable
Stable Release Date: 2016-07-18
Created 2016-02-28
Last Updated 2016-07-1816Hi guys what's up
Looking at the sheer number of times my kernel has been downloaded I have decided not to stop the development here not until kumajaya loses his interest in this device. The only reason I decided to stop development was that I was not fully satisfied with the kernel. No matter how hard I tried stuttering,lags and jitter were still there and with each and every build it got worse and worse along with new bugs like touchscreen unresponsive during charging n all.
So now I have decided to build the kernel completely from scratch. I have learnt a lot with previous berserks and now I'm going to improve upon them. The previous versions of berserk were more of fan service with tons of unneeded governors and schedulers. A fu**edup OC of 1.4ghz with no significant performance gains. Features like wakeup boost and hotplug boost which didn't boost at all.
OK I want to cut my speech in here and give you the download link to new fresh berserk
https://drive.google.com/file/d/0B2_mFAT8KtIZZFozbk04N3ZEUHc/view?usp=docslist_api
It's still at beta stage so most of the features are missing. As of now these are the only features-
*Linux version 3.10.49(will update to .100 in later build)
*no custom governors
*fiops is the only custom scheduler and this one is completely different from the previous one.
*faux sound
*intellithermal
*kcal advanced color control v2
*intelliplug v4.0 (this one is completely different. I have cherrypicked it from the original developer)
* -O3 optimizations (the previous berserk had O2)
*removed zram and zsmalloc
*frontswap, zbud, zswap and vnswap (these four are the first in any kernel for redmi 2)
And a lot more under the hood features.
So now I want all you wonderful guys to download the build and give me feedback.
Please don't report anything like my battery life is only 5hrs. On miui I used to 6-7hrs n all. I won't reply to all such comments. Remember this is not miui but a kernel which didn't have a source a few days earlier. Even the source they released is crap. Battery life depends on a lot of factors like if you are gaming expect a drop in battery, then whether you are using internet with WiFi or mobile data the latter drains battery fast. You may also need to calibrate your battery.
OK then bye goodnight and happy flashing.
Ah! Forgot to add the new source
