No. However, my beta build is ready [emoji14]

v5.0_b1 - Beta Release
Warning: TouchWiz ROMs only.

This isn't a final release, since I need to test things out with global users [emoji14]

For changes, track my new repo.

There's many more to-do lists before final build.

Edit: Now compiled with Linaro GCC 6.1.1 instead of Hyper 6.1.x SMxU which I used from v1.0 to v4.1.

Booted, but not usable. When it got to "Optimizing apps" process, every after 30-40 apps, it's freezing and restarted. However, the process was completed just fine. Same thing happen after boot. It just freezing and restart continously.
Btw, I'm using EthanROM v4 (PG1 based).

Current status would be updated. I feel some strange things while I test things myself this morning.

Edit: My test build 7 (v5.0_b1 minus several changes) booted fine on both my device and my tester.

Current news:
Seems like my source is messed up a bit, so I would restart some of my changes then.

Edit:
Seems that unstability has been fixed (DVFS related).

Edit #2:
And I couldn't test any further... :(

v5.0 would be EOL version for i9500. After v5.0 is released and stable enough, I'll end my development on i9500 unless state is changed.

What's being fixed?
1. Once-per-day reboot during idle on random occasions.
2. Hm...

Unfortunately, I have to discontinue my kernel development on i9500 from now.

My development (also main) notebook was stolen more than a week ago, leave me forced to use my old, slower netbook. Also, it's useless for me to keep developing on i9500 as if I do it, it would relatively same as others.

I now have a Xiaomi Redmi 3 Pro as my backup and development device, which I'm about to develop a CM-based kernel on it (if my netbook could compile arm64 kernel and if I get permission from the maintainer :p ).

See you in Redmi 3, and probably, other device's development. ;)

EDIT:
As the final stuff, I modified some parts of OP as per v5.0_b2 condition and KA.

    Downloads

    Installation instructions
    1. Make sure you've the latest version of TWRP or GearCM Recovery.
    2. Reboot to Recovery mode by combination of Power+Home+Vol(+) buttons.
    3. Select Install from TWRP screen.
    4. Select KudKernel .zip file.
    5. Swipe Flash button.
    6. Finally wipe cache and dalvik. (optional)
    7. Reboot to system.

    Known issues
    Don't report issues that are already listed here.
    • Kernel status changed from beta to experimental due to some unexpected behavior (continuous FCs, random reboots, etc.). Testers required to test every changes into kernel.
    • Sometimes, CPU will only bump itself up to 1200-1400 MHz. A normal reboot would fix this.
    • This kernel will negate any benchmarking app, since most debugging features have been disabled for best user experience.

    More to know...
    • Bug reports without good explanation or logs are ignored.
    • Request for feature(s) that could break stability aren't accepted.
    • You're not allowed to include my kernel as your work's default kernel. Instead, please include KudKernel Lite. (coming soon)

    Status & known issues
    • Totally rebased from a clean source.
    • Compiled using Linaro GCC 6.1.1 instead of Hyper 6.1.x SMxU which I used before on my v1.0-v4.1 kernel releases.
    • Synapse support is removed from the kernel. Use this script by @vishal thakar from now and so on. All bugs and issues regarding Synapse (except for errors due to unimplemented features) should be reported on that thread.
    • Negative Toggle seems do nothing when triggered. (probably won't be fixed)
    • [SRTIKE]Kernel booted, but would freeze in a minute or so, probably something went wrong with my new commits...[/STRIKE] | Fixed in v5.0_b2

    Hi everyone...
    I've read all suggestions and here's the currently workmap for the next version:
    Note: It would be potential for me to jump over to v2.0 due to upcoming major changes I've done.
    • Implemented UKSM v0.1.2.3
    • Unlocked all A7 frequencies
    • Set A7 frequency limit between 250-1200 MHz and A15 frequency limit between 1300-1600 MHz.
    • Porting Samsung codes to fully support GCC 6.0 (WIP; approx. 40% done); also need to tweak Makefile so it would skip some warnings because nothing could be done...

    It's all done on my very own PC now. It would be signed with a new RSA 4096 bit key and will available only on a .zip file based on download counts.

    And yet, I need to take a rest. It's late night here.
    Oyasumi~~
    If you need a spoiler about what word is this:
    Oyasumi is a Japanese word that means good night.
    A bit off-topic, is it?

    Change init.container.rc from my ramdisk and it will fix your private mode problem. About default governor do not change from default governor parameter .defconfig change with .sh and it will set some needed parameter with ondemand and change with interactive. Good luck

    I'm trying to implement Synapse support into the kernel, plus Indonesian localization :D

    Hope it's going well guys!

    A spoiler attached :p
