Hi voku . I flashed and tested this on AllianceROM v7 LSD rom which I did a full wipe installation of last night and was running fine on jeboo kernel 1.3b.
After flashing this test kernel On stock settings I was browsing Tapatalk and I experienced a screen freeze.
Had to hold down power button to come out of it and reboot phone.
I experienced the same thing on a kernel compliled by solar1 2 days ago from initramfs and pm Dorimanx about this. This was on LS8 based version of AllianceROM.

In developer option enable force gpu rendering. Will fix, I used to had this problem and this trick solved my problem.
The domino effect "out of thread" posts create when followed by the smart guys answering them to go to the discussion thread creates a whole more mess than what we had with noobish already answered questions. Guys let's face it, reporting issues and asking questions in the same thread where Kernels & ROMs are posted is the way things run at XDA. Is just common sense and is the way it is designed to work.
I know the intention is to keep things organized but IMO is not working. Now we get at lest 2 or 3 "Go to the discussion thread" post per pages cuz someone didn't followed the rules. Answering noobs is easier than forcing everyone to use the discussion thread.
Personally I don't think is too much problem to answer someone's question and the tell him to use the discussion thread next time. I'm completely in favor of using the discussion thread but is very annoying to see moderators here every day deleting posts and 2 or 3 guys telling everyone that didn't followed a "rule" to "get out here, wrong thread".
This used to be one of my favorites threads, lots of discussion and sharing ideas. Now it has turned like into XDA's dictatorship. Follow the rules or get out here type of thread.

First boot everything runs smooth, no freezes at Tabatalk (like Red Blur). So I make a Antutu Benchmark after finish it, I got a freeze on Homescreen. I had to hold down power button to come out of it and reboot phone. Then I do two times an Antutu Benchmark with no freezes.
What kernel-profile did you use? (Dori changed some gpu settings for "performance"-profile in the last hours.) I will also run some benchmarks, for testing stability ... thx for testing!
PS: I read more posts about "this thread" on the last pages, instand of something that interests me

Stweaks settings won't remain for "I/O", "Memory", "Other" & "Tweaks" tabs and also touch freq and 2nd core freq
they will reset after reboot to their default selected profile values
Rom: XWLSD
Kernel: 7.47 beta (voku)
p.s: wifi toggle from 21502 post detail is also a problem on my device

@voku
I'm using your test kernel and got zero issues with it
here is a smal test i did opening apps to test what upu asked.
Anything more just ask.
Thx for reading & answer my request
I will take a look at the killed apps ...---------- Post added at 09:40 AM ---------- Previous post was at 09:21 AM ----------
Thx for testing & reporting bugs!!! I opened a new bug-report at github for you, so we have a overview about bugs and others can see that it's already reported (and everybody can add more info, logs etc. at github to improve the bug report) -> https://github.com/dorimanx/initramfs3/issues/4

PS: I read more posts about "this thread" on the last pages, instand of something that that interests me
It was after first boot with test Kernel, no changes everything stock !!!
What ROM (+version) do you use? PS: I am still using CM 10.1 (20130103) and haven't this problen?! If you have the Wifi-toggle problem again, please take the screen off and on again (only for testing)
and please add a debug-log next time, you can create it via STweaks - And then create a full bug-report at github -> https://github.com/dorimanx/Dorimanx-SG2-I9100-Kernel/issues?state=open

Dorimanx Kernel for SGII-I9100
Supporting 5 ROM Platforms!
My kernel was based on SiyahKernel 4.0 long time ago in other realty,
Kernel Tree is 3.12.rc6-R101, + Samsung JB updates + my tweaks and lots of tuning!
Thank you Gokhanmoral for your great work in the past!
Warning!!!
Do not install this kernel on any Android version lower than 4.1.Y
Do a Nandroid Backup of your ROM before first try it! just in case
Constant OC will drain more battery! use low speeds on screen off! min 200/100 max 800
CPU will shutdown in case of over-volt or under-volt so be careful
I'm no responsible for any hardware damage or system corruption that can happen after using this kernel,
you are using this kernel from your own will and accept any responsibility by using it.
If you install this kernel your warranty will be void!
Of course you can be relaxed, I'm trying every release on my phone several hours before of release it so,
if something wrong, i will get the damage first, you get a tested and tuned working kernel...
« Thread rules
« Which kind of posts are allowed in this thread?
- Report of bugs after test it personally and including the proper log (Please refer to the Voku's guide of How to report bugs for further information about logs.)
- Feedback that could genuinely helps to the development of the kernel, for example tests of a new feature including a complete explanation, documentation and results.
- Requests of new features for the next versions of the kernel with the proper explanation of why you expect to see it and why do you think that will be an improve to the kernel.
« Which kind of posts are not allowed here and belongs only to the discussion thread?
- Battery life related, which include: Discussion of battery life, statistics of your battery life, screenshots about your configuration, your configuration itself (with the intention of help another users)
- Reports of SOD if you undervolt / overclock your phone
- General discussion about settings of the kernel, which include: Governors, schedulers, I/O, dual-boot, etc.
- Requests of new features for the next versions of the kernel without the proper explanation of why you expect to see it and why you think that will be an improve to the kernel.
- Bug reports with the proper attachments like logcat and kernel log (This is the exception, you can post it here and in the development thread, again, only with the log attached, otherwise the report will be ignored), please refer to the voku's guide of How to report bugs for further information about logs.
- Deep sleep issues. Mostly of this issues are not kernel dependent, the rogue apps cause wakelocks and other weird behavior so, the first suggestion will be go to the BBS (Better Battery Stats) thread, install the app, and drop the log in there but as complement you can expose your issue here.

I am calling Vikas(vikas.mishra) to the speech stand
Hello people.
Let me introduce myself - my name is Vikas Mishra and I am a chip designer by profession. .
I have worked on critical parts of design of TI OMAP4, OMAP5, Nvidia Tegra 3 etc and have been doing this for the last 14 years.
Of late - I have seen a lot of folks posting BUGS about undervolting of the GPU/CPU.
I think I can explain what are the possible issues with undervolting/overclocking in a laymans language.
It is a little long winded but I think the length is needed for providing the appropriate context.
* What is inside your Cellphone
Your cellphone is an amazing device. It is a full fledged computer
that fits into your pocket. They have all the standard components
that a computer has - except that they are all usually soldered on
the motherboard directly and are not meant to be user-servicable.
The chief components inside your cellphone are
1. Application Processor (AP)- this is the heart of a modern
cellphone. These are manufactured by many companies - the main
ones are Qualcomm, Nvidia, Samsung and Apple. The other not so
well known ones are made by Texas Instruments, ST Ericsson,
Marvell and Broadcom.
A modern AP has logic to control the camera and process the image
that it generates, to do video encoding (video recording) and
video decoding (movie watching), Audio processor etc. in addition
to the well known CPU and GPU.
2. Power Management Controller - This is the chip that is
responsible for generating and regulating the voltages that are
used by all the components on the board.
3. DRAM - not very different from the DRAM found on a PC (except
that it is lower voltage)
4. Flash - for storage
5. Touchscreen controller
6. Logic for microphone, speaker
7. Battery
One of the most complex piece of circuitry on the phone is the AP
and the power management controller.
* Circuit Basics
A modern AP has millions of circuit units called (Flip
Flops). These flip flops have two parameters associated with them
called Setup time and Hold time. More details on what a flip flop
can be found on the wikipedia at
http://en.wikipedia.org/wiki/Flip-flop_(electronics) . This is a
nice bit of bedside reading if you are interested.
A setup time roughly indicates what frequency you can run a design
or an AP at before it becomes unstable.
A hold time roughly indicates the maximum voltage till which a
design is stable.
A fully technical analysis of what is involved in these timing
parameters requires a degree in electrical engineering but in broad
terms the problem is described below.
Chip designers diligently ensure that all of the millions of the
flip flops in a chip meet the setup and hold time across a broad
range of voltages and silicon parameters. They do a pessimistic
analysis to ensure that a chip will run reliably across a wide
range of voltage/frequency combinations.
However, contrary to the popular belief, chips vary widely in their
silicon parameters. Even chips on a the same wafer and different
flip-flops within the same chip can have widely different silicon
parameters. This is why what works on one particular chip will not
work on the other chip.
Your silicon manufacturer provides a range of voltages and
frequencies across which the device can work reliably. The phone
manufacturer will further narrow down the range depending on the
other components they choose within the phone board.
* How does voltage affect the design
Reducing voltage makes the design slower and increasing voltage
makes the design faster.
So can I keep on increasing the voltage for ever and make the
circuit faster and faster. The answer is no - a point will come when
the circuit will become unreliable. This becomes unreliable because
the "hold time" of one or more of the flops will start
violating.
As you reduce the voltage of the design, the circuit will start
becoming slower. However typically it will continue to work till at
apoint it starts failing - this failure occurs due to violation of
"setup time" of one or more flops in the design.
So what happens when the setup time or the hold time of a design
fails - the answer is that it is unpredictable. Meaning suddenly if
you ask the processor what is the value of 2+2, the answer it will
provide could be unreliable - in some cases it could be 3, in some
cases it could be 4 in some cases it could be -2349783297 (a random number).
I am of course oversimplifying but I hope you get the picture.
* How does undervolting affect your phone processor
The reason undervolting is so appealing to people because they
thing that undervolting will save power and improve battery
life. While this is true in theory, in practice there is a caveat.
It will reduce the power of the chip, but the power consumed by the
phone as a whole will not improve. In some cases in fact it can
deteriorate. Let me explain.
The most power hungry part in the phone is not the AP - it is the
LCD screen. All of these screens consume a ton of power. So even
though your AP is now consuming lesser power, the overall impact to
the phone as a whole is not that much.
If you accompany undervolting with a frequency reduction (which you
should), the total time taken for doing a web page rendering (for
example) would increase. During this time the screen is on and it
has more than compensated for the power that you saved in the
AP.
You could of course come up with examples where this wouldn't
happen - but on a whole, IMHO, you should leave the voltage of the
AP/GPU/CPU to the guys who know the system best - the guys who
designed the chip and people who manufactured it.
* How does overvolting/overclocking affect your phone processor
If you want that last drop of performance from your phone and you
over clock it, at a point some of the design flops will start
violating the hold time and the design will stop working reliably.
Again, in some anecdotal cases this would work - but this is not a
reliable means/mode of working. Just because your friend's or your
first cousin's girlfriend's phone works - doesn't mean yours will
work as well.
* What are the user observable impacts of undervolting/overclocking?
It is hard to say - simply because there are so many of flops in
the design.
In some cases - you wouldn't see anything wrong with the phone
until one day you do. In some cases it will result in a SOD
immediately. In some cases it will result in your phone not waking
up reliably.
IMHO the risks of issues with undervolting/overclocking far
outweighthe potential gains you may get out of it. Usually there
is no lasting damage to the phone/AP if you overlock/undervolt but
it is possible to do it. For example, You run the phone at such a
high frequency that the chip temperature becomes more than what it
was designed for and the Silicon just fails.
So "Just say No". Don't overclock or undervolt your phone -
leave it to the guys who really understand what they are doing.
Thanks,
Vikas233News update!!!
Kernels 8.14 + 9.14 ONLINE!
Kernel is STABLE with good performance + good battery, we worked very hard on this one. (Me and Voku!)
Change Log:
*Voku updated Interactive CPU gov and enabled it. (need to test!)
*Voku updated/Ported many system code and ROW I/O sched tuning.
*Voku Ported and Tuned and reconstructed new CPU HOTPLUG code,
it's name is Inteli Hotplug, originally made by Faux123 for his OMAP device.
this new driver will help to save more power and give us nice performance.
*Voku Ported 3.0.72+73 Main Stream patch's.
*Voku Tuned cortex and profiles to mach new drivers.
*Updated to latest Linaro 13.03 kernel builder.
*Added new EDS module to allow using EDS paid/lite app to encrypt data on your device, module can be loaded via app or via STweaks.
*Allowed to use 1450mV for 520Mhz GPU freq.
*Equalized last CPU chip Voltage table (number 1) to have same CPU voltage as others!
We have 4 different CPU chips all over the world in same device! now all will have same voltage, this will allow higher OC and better battery save for all.
*Added +25mv to 1500mhz and 1600mhz for all chips. to give more stability.
*Updated many CORE and MEM code from 3.9.y kernel.
*Updated many SYSTEM code from 3.9.y kernel.
*Updated many CPU and SMP code from 3.9.y kernel.
*Added auto read ahead tweak, based on sdcard size!
*Updated INIT boot from latest CM-Kernel for 10.1 based ROMS.
*Cleaned old standard hotplug settings and script code.
*Added some STweaks better descriptions in BLN.
*Limited battery charge mA to 650mA, we cant get more any way, hardware limit! no way to have MORE, so 700mA was actually 650,
and we can have MIN of 450mA so no need to ask to set lower, it's will not work.
More can be seen in GIT, for all that love to dig deep
Have fun, and Report = good debug info!
Thanks!
do not REPLY to this POST!201News update!!!

This Kernel is A MAJOR update! i have never done such big update before!
We need to test all we can.
Change Log: (i cant write all, it's too much! see gits)
*Voku ported new CPU GOV = ZZMOOVE it's good gov with HOTPLUG ability's and smart cpu management on sleep and wake.
for now no controls for it in STweaks, but you can select it.
*Voku ported new Ultra KSM code from 3.9.Y kernel, it's still in tests, we will see what good we can get from it, read google what is KSM (shared memory control with many apps)
*Voku tuned the Dynamic CPU freq on touch, seems to work good.
*Voku ported kernel patch 3.0.74-76 from main stream.
*Voku ported System code for ARM CPU and system.
*Voku tuned profiles for interactive GOV and other stuff.
*Till we can fix slide2wake to be off in call, it's OFF by default in all profiles.
*Voku ported good patch for Interactive CPU GOV. we need extensive testing.
*Voku ported updates for ROW and NOOP I/O scheds.
*I have made FULL sync of all new code for RAM from 3.9.y Kernel. we have all
*I have ported major update to filesystem + kernel main code + lib, from 3.9.y branch. (it's HUGE update!)
*We have fixed some small bugs in scripts.
*Voku added function to add DATE and TIME to kernel LOGO on each kernel release! that is very COOL
done by auto on kernel build.
have fun, report and test all you can,
RAM performance is now X2 and cpu power is awesome!
battery is holding longer!
it's for now great kernel, but need more time to know that this is STABLE release.
P.S
if you like my hard work, buy me a beer (my beer account is empty )
Thanks for waiting
I hope you READY to see the PICKS
HTC ONE X in the TRASH
performance profile + rootbox 22/04/13 nightly
==========
After some more tests i have fixed some more and tuned profiles.
ALL, please update to 8.16 + 9.16 kernels! (online)
Change Log:
*Voku ported Interactive GOV as is from Google Android Kernel 3.4
*I have reset profiles to not use Interactive as main Default GOV, as it's may be unstable for some users. (profiles will be reset, on boot)
*I have ported major function update from 3.9.y kernel to fix the Ultra KSM and much more.
*I have set HZ value to 250 (was 200) it's effect globally on system performance. and it's best default for android.
