I'm just after quick test of my altered kernel (reduced undervolt). Unfortunatelly it is not enough to increase voltage, I had to disable the lowest frequency (150M) as it tends to make reboots during long calls. After that I had no single reboot at all.
[Galaxy Ace S5830i Android Development] meydon:
I have already flashed mine back to stock kernel, i dont like the reduction in the size of the ram.

Please can anyone tell if I can get init.d on stock kernel? Cause i intend flashing Cronmod script? :cool:

[Galaxy Ace S5830i Android Development] morrisx:
You can get init.d support to a stock ROM. I'm using it, on my stock one. U should search on xda. When i remember well, the name of the script is something like this: term.init. probably it will not work for the first time, read the last few comments on the original thread, how to solve it.

Sorry for my really really bad english
[Galaxy Ace S5830i Android Development] Androidnow:
Got one random reboot with the new kernel. Will test further and report. Same 3G problem.

Update :- Another reboot during a call. Bug persists. :confused:
[Galaxy Ace S5830i Android Development] LaShto34:
No, this only happens sometimes. At boot sometimes the cwm and rzr versions of kernel have problems with ext4 format of internal memory (can't mount data or cache partition - or something like that). That's why rafael recommends the E3 version. But in this case we must have rfs format of internal memory. Which means we must reinstall stock rom via odin to have back rfs format, etc... Maybe this will be fixed. From my point of view it's the only bug that's left. But I don't know if can be fixed, or it's an "ext4" problem, that doesn't depend on kernel.

By the way I don't have the reboot problems. But I always stay on 2G (I switch on 3g only for internet browsing - for the battery to last longer). So maybe it's only a 3G problem, which means that it's not a kernel itself problem, but the modules. I'm just saying, if I'm wrong please don't get upset on me.
[Galaxy Ace S5830i Android Development] Alucard1989pl:
So, why Rafael make the possibility to format /system, /cache and /data to ext4 if the rfs file system was good and safetly for recoveries, backups/restores etc.?? :confused:
[Galaxy Ace S5830i Android Development] LaShto34:
I don't know, maybe because he let's us choose what we want.

Anyway, here is what he said:

Because I really hate to reinstall a rom (to have rfs back) I will just wait to see if he can fix that. If not, I will go back to rfs (and use his E3 version). Anyway, this problems appear only sometimes...

[Galaxy Ace S5830i Android Development] demis95:
hello, I am creating my rom, I would like to put the latest version of the kernel ... how should I do? and which version should I get?
[Galaxy Ace S5830i Android Development] maciej_s20:
After a few days of testing this is howto avoid reboots on s5830i with Rafael's kernel:

1. Disable 156MHz frequency - allow to scale CPU from 312 to 832Mhz. Best way to do this is to install "No frills CPU control" from google play

2. (optional) Increase voltage in kernel sources and re-compile it. This is easy if You have Ubuntu as scripts are prepared for this system. My values can be found in one of my previous posts.

After doing this I had no single reboot. Works 100%. I'm not sure if step 1 without step 2 will help much, but can guarantee that doing both will solve Your problems.

Quick backgroud (what I suspect):

1. Not every phone is ready for low voltages introduced by rafael. Some of them needs higher voltage - this is first source of reboots

2. It looks that some of s5830i does not like 156MHz, especially during call. Rafael has added this frequency for longer battery life, but as we can see it was not a good move for all the phones.

hope this will help You.

Maybe Rafael could create new build with those settings applied? I don't want to post my build of the kernel...
[Galaxy Ace S5830i Android Development] bestson:
Any one have this issue ??? during turning off/on wifi the mac address is changing (spoofing) :confused: it make me always do registered my mac to the system... :D

[Galaxy Ace S5830i Android Development] Miche1asso:
I am the developer of the Cor Plenus kernel for Galaxy Next Turbo/Pop Plus Mini Plus (3 different names. Don't blame me, blame stupid Samsung). Same bcm21553 CPU of galaxy Ace-I.

Just to let you know that I have been facing exactly the same identical problem, I fixed it a couple of days ago removing the 156Mhz frequency once for all. raising the voltages did not improve a single thing. It seems the HW doesn't like the extra frequency under mode 0x0B, below mode 0x0C for Normal, 312Mhz, frequency.

I reached the conclusion that this is the worst piece of HW in the whole Android world.

The latest kernel (#201211201515) is working perfectly with the E3 version! Thanks Rafa! :D
[Galaxy Ace S5830i Android Development] ilsaggio73:
with or without modules?
[Galaxy Ace S5830i Android Development] kouss77550:
With the modules.

But i've done the cleanest install I could've done :

1) Flash a

stock ROM

with

stock kernel

with Odin

(XXLA2)

2) Flash the

E3 version

of the kernel WITH ODIN.

3) Wipe Data, cache, dalvik cache thru CMW

(BUT NOT FORMAT)

4) Install the custom ROM (for me Mind_Cr v2.3) and directly install the E3 version of the kernel with the modules before rebooting

5) Reboot and enjoy! :)

That's it. Excuse me for my very bad english, hope this will help! (yn)
[Galaxy Ace S5830i Android Development] LaShto34:

That's exactly the same thing I did. And I can confirm that this latest version of the E3 kernel is working perfectly. Thank you Rafael, once again.You are a great guy. By the way, I apreciate the fact that you are not too proud, and accepted to remove the kernel boot logo. Now this kernel is perfect. I don't have any reboot problem using 3G. My settings are: 312-832 MHz, smartass v2 / sio.
[Galaxy Ace S5830i Android Development] bestson:
mind used cwm ext4 is... working great.... as rafa mention on how to install.. no more reboot during call but for some reason since I am using the script for data2ext.. it's fill little bit slow.. but not so sure if it's slow or just to many application running... due to limited memory :silly:

How can I update busybox in that kernel ? I used busybox installer from market but always have error ...
[Galaxy Ace S5830i Android Development] ilsaggio73:
I do not want to change rom ... so I just install from recovery 201211201515-E3-boot.img.zip, reboot recovy and install 201211201515-modules.zip right?

and there is the problem of restarting the phone during a call?
[Galaxy Ace S5830i Android Development] GermainZ:
From my experience, it never flashed itself correctly unless I did a clean install.

And the rebooting problem is tied to the 156Mhz frequency, disabling it is enough to fix it.
[Galaxy Ace S5830i Android Development] ilsaggio73:
ok, but I can do as I wrote above? and after doing wipe cache? I have always done so, the phone is of my girlfriend, I can not put the stock rom
[Galaxy Ace S5830i Android Development] makeyourself:
The thing is is that the kernel installs busybox to the /sbin folder which, if I'm not wrong is part of the ramdisk, i.e. you can't easily change it without losing the changes every reboot.

I updated it manually in recovery, pushing 'busybox' to /system/xbin and executing 'installbusybox' via adb, but then I had to put a script in /etc/init.d to overide the /sbin busybox binary!
[Galaxy Ace S5830i Android Development] lojpek:
I deleted old busybox and install from market stericson busybox installer and it works well but rafael.baugis can update it in next release :)

For all of you having trouble, it might be worth mentioning that flashing using ODIN was straightforward and caused no problems for me, unlike flashing via CWM.

Just grab the ODIN download, reboot your device in download mode, open ODIN & select 201211201515-E3-PDA-boot.img.tar then hit "Start".

Oh, It says "This Kernel version 2.6.35.7 is compiled from Samsung sources, with GCC 4.4.7 compiled from ubuntu sources." in your first post

Anyway I tried installing todays kernel but I can't get past the "model logo screen" (still boots to recovery, but not to the ROM). Followed the steps exactly as you said in your post (even wiping data cache system and reinstalling rom)... Your older kernels that came with modules and boot.img together worked fine (I didn't try any zip between those united kernels and this last one as I didn't update for a while)

edit: Says "error mounting /system" after I used CWM to format it... Eh, odin time I guess
[Galaxy Ace S5830i Android Development] Rafael.Baugis:
install Kernel-CWM, format /system, /data, /cache and install ROM then reflash the Kernel-CWM
