You are completely right. It is unpossible. I like the possibility of configuring colors (mainly to have darker screen at night)

But now i'm not quite sure if i want it.
[Galaxy S I9000 Android Development] Fenvarien:
Yes, just remove the ".txt" extension and set the 777 permissions with root explorer.
[Galaxy S I9000 Android Development] wassk:
i can say that this version is not for my phone.i ve tried all sort of thing that u guys write here on forum.but my phone lags like **** with this version.OC or not.and the screen freezes with some sort of yelow tint on in. im trying this for two days and no luck. back on 1.8.2.
[Galaxy S I9000 Android Development] Fenvarien:
@wassk

Try to wipe dalvik cache and cache partition - this solved it for me.

I don't know why my phone had hick-ups and a higher battery consumption, but now it is running just perfect and with great battery life.
[Galaxy S I9000 Android Development] oserx:
@stratosk - your latest kernel gives me headaches. All respect for your work, but without any tweaks, only the ones in Semaphore .. the phone behaves really crazy ... random long (1-2-3 seconds) lags, etc ... etc ... Really don't know what to do .. In my opinion 1.8.0 is your best kernel, followed by 1.8.2 ... and 1.9.0 beta...1.9.0 final is final ..
[Galaxy S I9000 Android Development] flolep:
??? No problem of this type for me and 1.9.0 is really better than 1.8.0...

Also reboot :-(

Good morning,

I also faced first time since on Semaphore an uncontrolled reboot yesterday night.

Was using ondemand with simpleIO, now switched to deadline scheduler. Lets see if that was the root cause.

Hm....

Cheers

[Galaxy S I9000 Android Development] darckengel:
I don't have any problems too...

@stratosk:

I tested the music player with and without DVFS, each time for 8h (a whole night playing music each time :) ). And I had the same results that with the tests i made months ago, the same consumption for the 2 versions: it uses about 1%/hour, so removing the DVFS don't reduce the battery usage of the stock kernel, i'm very surprised !
[Galaxy S I9000 Android Development] stratosk:
Hi,

It was a random reboot? Did you use any application? Do you OC?

You may also try noop scheduler.
[Galaxy S I9000 Android Development] stratosk:
I think I should try harder, because the kernel becomes worst and worst in every new version. :)

Are you sure that this is not related to your ROM?
[Galaxy S I9000 Android Development] darckengel:
I don't think that the kernel is going worst...

I used all version of Semaphore, never had a problem, OC to 1.3Ghz, UV on all frequencies with no problems, all is very stable.

Not sure that the few cases that have problems are really kernel related.

First all phones are differents and reacts differently on the same conditions, your phone getting older will be more solid, and having your phone OCed will make your phone aging faster. So as lasts versions of Semaphore are more responsive, maybe your phone can't just support the extra effort.

Second, many people here tests all the things that comes, roms, kernels, scripts.

It's hard to compare kernels versions, if between 2 you have switch roms 3 times...

And even with wipe versions your phone is never clear when you go to a new rom (unless you also wipe your internal sd...)

Personally, i used the same rom for months (an odexed JVS rom very closed to stock but with some personal tweaks and theme), so all the Semaphore kernels i used had the same conditions. And as my rom is very stable, if a new kernel is not as stable as olders, i can be sure that it's kernel related, but i didn't had such problems...
[Galaxy S I9000 Android Development] gsw5700:

This is by far the best kernel the recorded history has ever witnessed!!!!

i have used every kernel and i mean all,not only in xda forums,i am a power user and the only kernel that is fast and STABLE is the semaphore.

i am really proud that a greek fellow has created this gem.

jvt1.9.0 doesnt root my phone why?
[Galaxy S I9000 Android Development] betoNL:
Internal voltages, core voltages, it's all there on my guide.

I dont know how voltage control app is doing nowadays. I did try it in the past, I even bought the donate version....but I didnt like it, it was too buggy.

I tried all kind of OC/UV apps and decided to stick to Tegrak Overclock Ultimate.

Now on my guide you got 3 options of settings:

Right now I am using the one up to 1180 MHz...

On 1200MHz my phone was getting some stability problems but only when listening to music on screen-off and opening it, cause that's when phone tries to go in and out deep sleep

But that's on my sgs, which always have been tough to overclock

On 1180MHz setting ( the second option on my guide) everything is fine, deep sleep, music on with screen of and on etc.....

http://xdaforums.com/showthread.php?t=1250442

If you try it, give your thoughts over there...

Right now my sgs is having the best battery performance EVER.....

@stratosk

Please don't change anything, I am struggling to find issues :eek:

[Galaxy S I9000 Android Development] Nergla:
Have been following this thread since summer and flashing kernels as they were released. Never once burnt my fingers and am now running latest release. It is rock steady and flies. Semaphore in my opinion gives SGS a new lease of life and I no longer feel the need to upgrade the phone. Big thanks to Stratosk and the active participants in this project.
[Galaxy S I9000 Android Development] andip71:
No. Just do slight undervolting, but same for past two months.

No issue. I will keep an eye on it.

Andi
[Galaxy S I9000 Android Development] stratosk:
Please download superuser application from market.
[Galaxy S I9000 Android Development] McDown:
It does root but you have to download Superuser app from the market yourself.

edit: Damn, stratosk, you are faster :D
[Galaxy S I9000 Android Development] stratosk:
I think maybe this is the problem. I mean using the same undervolting settings.

Newmail's patch to ondemand governor changed the cpu frequency behavior. Before 1.9.0, 800Mhz were slightly used. But now it's the max frequency when your phone's screen goes off.

Please try to reset your uv settings and check if the problem persists. If it is ok, start to decrease the voltages but having in mind that 800MHz is now frequently used state and it must be also slightly (or no) undervolted.

I was thinking also to overvolt 800MHz because of this just for testing.
[Galaxy S I9000 Android Development] jocke_lulle:
For the last 8hours ive been using 1.8.2d with the screenstatescaling script darckengel posted. I have oc 1200mhz and -25mv. So far so good, no freeze or reboot (which I had with 1.9.0 ). Im going to keep testing the phone and see if it stays stable.
[Galaxy S I9000 Android Development] stratosk:
Can you please clarify if you noticed, which application (or kind of application) caused the reboot? Or it is random?
[Galaxy S I9000 Android Development] jdogzilla:
Guys, using Semaphore 1.9 with FI Innovation ROM, and my phone is DDDRRRRAAAAGGGGIIIINNNGGG!!! BetterBatteryStats shows a big red line for "mmcqd" followed by "kswapd0" ... any suggestions? Is there some setting that I should apply? Any suggestions would be helpful?
[Galaxy S I9000 Android Development] jocke_lulle:
It has been random reboots for me. But i know that it has happened with stock-sms and xda app.
[Galaxy S I9000 Android Development] betoNL:
Yes I have a suggestion...

Move on to another rom

The best is on my sign

---------- Post added at 07:19 PM ---------- Previous post was at 07:17 PM ----------

You didnt try my guide, did you?
[Galaxy S I9000 Android Development] jocke_lulle:
No not yet. I thought i would try the 1.8.2d kernel first (with screenstate scaling script to get oc to work) to see if it worked (which it seems to do) and if so maybe make some conclusions about why 1.9.0 doesnt work. It seems like a few other people also got the same problem.

Btw, I read your oc/uv-guide and it was very easy to follow. I will probably test it after I have tested this kernel-version a litle bit more. Thanks!
[Galaxy S I9000 Android Development] andip71:
Hi Stratosk,

thanks for the very helpful explanation, I guess this is good to know for everyone.

I have now taken back the UV from 800 MHz step at least and will monitor over the next days.

By the way: Had a good laugh when I read your comment about Semaphore getting worse and worse. Not at all. It is the best and universal GB kernel for the i9000 out there. Really glad you do such a great work!

Cheers

Andi
[Galaxy S I9000 Android Development] darckengel:
If 1.8.2d works, it's not due to newmails patch, as it's included in this version.

Maybe it's from the rom, as i understood you had problems with this kernel (cannot use the scripts to set max clock at 1.2ghz) and you install a fresh rom, maybe it has solve the issues with 1.9.0 too.
[Galaxy S I9000 Android Development] stratosk:
Hi again,

I really don't know if this is your problem. Just a guess. There are 2 major changes that maybe could cause such problems.

1) Newmail's ondemand patch

2) 341MB memory configuration.

I doubt about the second (but you never know).

Thank you about your comments. But really, I respect everyone's opinion. I can't say if this the 'best' kernel or the 'fastest' or 'smoother' or the 'worst' or the 'slower' or the 'most laggy'.

I do know and I can say that I'm trying hard for this and I really test every single version and only if I realize that I don't face problems I will release the version.

I'm using only stock roms (shame on me - I've never installed a custom one) because I want to test in a pure environment.

Right now I'm on stock JVT without a single mod or tweak. I always use 1.2Ghz and ext4, 99% to ondemand and noop. Honestly, it's stable.

I understand if someone has problems with Semaphore and I will try to improve and minimize issues with the right feedback.
[Galaxy S I9000 Android Development] betoNL:
No mods? Not even integrated SIP? Some Perka's mods? UOT kitchen?

I know that some mod roms do more evil than good, but some mods we need ;)
[Galaxy S I9000 Android Development] stratosk:
No mods, no tweaks. Just pure JVT.

I don't say that mods are evil or that all mods causes problems. I'm saying that I want a pure environment to test the kernel.
[Galaxy S I9000 Android Development] jdogzilla:
How confident are you that this ROM will not give me the mmcqd problem?
[Galaxy S I9000 Android Development] GreenSGS:
As you know,I am one of the victim of random reboot. I have few points to make.

1. No OC, ondemand,noop, no reboot.

2. No OC,ondemand,sio reboot

3. OC, smartassv2,sio or noop reboot

4. OC,ondemand,Sio reboot

5. OC , ondemand, noop yet to test.(Well I tested it once but phone was off during a call,may be it was low batter thats why I said yet to test)

I can confirm,the sudden freeze color fade happens only once after you flash the kernel. After that all other rabdom reboots are just freeze or silent reboot.colors stay.

May be you can get hint out of it.for me its overhead projection.

I picked no oc,ondemand , noop for somedays as I needed phone on & available, back to experiment.

Thanks

[Galaxy S I9000 Android Development] betoNL:
As Stratosk, I always used only stock roms and only changed kernels and apply some mods myself like integrated sip or a modded swype no major modding...

But then one day. I decided to give Criskelo's rom a try and it was great...

Cryskelo left the sgs and Lirik continued and even improved his work..

You can give it a try...his roms are always "no wipe", but in your case I would suggest a "fresh" install.

If you dont like it you can always go back to whatever you were...

Just some more tips.....after flashing it, run it for a while, feel how it goes, before rushing to convert the file system... I have nothing against ext 4, even the "virtual" ," converted" one, but sometimes things can go wrong during the conversion itself, so why risk it , since rfs is much optimized since Eclair and Froyo.

Also be aware of too agressive LMK settings and superfluous "scripting"
[Galaxy S I9000 Android Development] GreenSGS:
Cache cleared, dalvik cache cleared, not tried set permission(never read what it does! But I'll),only semaphore no other tweaks. ROM is stock JVT,never ever had custom rom.

Hello

I have a problem, namely the JVT ROM (clean / custom) after uploading 1.8-1.9 Kernel Semaphore someone calls me and I bell is not working my mic (I have to turn off the speakerphone and then starts to work).

problem no.2

When installed him Luncher EX and IT manager of SMS SMS Pro is a problem with blocking using the formula (after only one phone model and asks for so much later now enter without)

Someone has something similar? There is a solution there?

[Galaxy S I9000 Android Development] darckengel:
jocke_lulle has no more reboots with 1.8.2d and it's include the newmails patch.

mmcqd is the daemon handling the sd card queues (read/write). Check your external SD (if any)

try to unmount it and try the operation without it.

OK, so far:

latency (40000) tested with first test version and you still had the problem.

With the second test version you will test the 336MB.

Hi. I just wanted to let you know. I flashed 1.9.0bm yesterday evening and now i had one of those reboots with washed out colors (i opened a document with thinkfree office).

Settings: oc1200, uv-25mv, noop, ondemand.

So the problem isnt due to the extra ram (341mb) neither i think.

For now im going back to 1000mhz.

So,

It seems not to be related to extra memory added (GreenSGS have reboot with the test version) neitheir to newmails patch (jocke_julle don't have reboots with 1.8.2d with newmails patch) ....

I don't any adea left ...

GreenSGS, can you try 1.8.2d as jocke_julle did? and standard 1.8.2 again?

You two could have differents problems

Hey Green,

Just for the sake of research:

If you ever came from froyo, did you ever flash gingerbread bootloader?

And if you did, also for research but also curiosity, are you on rfs or ext 4?

Try flashing GalaxyRom_v12 and see what happens....it's a "no-wipe" install, meaning user data remains intact.....but it will probably adjust all that scripiting stuff....(to make a long story short)

You have nothing to lose if you give it a try....
[Galaxy S I9000 Android Development] stratosk:
I'm really try to understand the cause of this issue.

If you have time please test also the 1.9.0beta

I'm sorry for this, but we need to narrow down the problem.
[Galaxy S I9000 Android Development] GreenSGS:
Dank u wel, I have gb bootloaders and I am on ext4.

hmmm GalaxyRom_v12,I was reading it yesterday,I will try install tonight,Its using semaphore 1.9.0 so +1 already.no wipe is good,do I need to be on RFS?
[Galaxy S I9000 Android Development] jocke_lulle:
As im also having this issue i also try 1.9.0beta. I really cant remember if i had problems with that version but lets see:)
[Galaxy S I9000 Android Development] GreenSGS:
Thank you. Its like blind folded finding a black shirt in dark room

I do it right away before I flash GalaxyRom v12.
[Galaxy S I9000 Android Development] GreenSGS:
Please do test and report.
[Galaxy S I9000 Android Development] betoNL:
For the experience and because you gonna flash a new rom, convert back to rfs, flash the rom and feel how it goes on rfs, lets say for a week....then try ext 4...

And Lirik's rom is.....zeer aan te bevelen ! ;)

Succes!

Edit: Actually, since you are having issues ( that I , for instance dont have), Install JVT fresh, than flash CF Root in order to achieve root and the built-in CWM, then flash GalaxyRom_v12

Off course you can always try to flash GalaxyRom_v12 right away, without all these preps, but then , at least, re-convert to rfs first

I am very curious about the results, thanks for trying

Over 20.000 downloads of this kernel version.. 1 or 2 report this issue.. What is the most likley cause? Kernel problem or other things with your setup/rom/twaeks/apps..

[Galaxy S I9000 Android Development] pikachu01:
Are you Uving by any chance?
[Galaxy S I9000 Android Development] hackeron:
I probably expressed myself sloppy. I have no problems.. I was just trying to point out that the reboot problems that this user had probably is not kernel related because it seems to work fine for a vast majority of us.

I use SIO/Ondemand without any problems.. And I use UV -175/-125/-100/-75/-50

Starting at 100mhz.. Everything works superb.

Actually, right now the latest version has about 33000 downloads (about 10000 from semaphore.gr). Thank you all for your trust. :)

But anyway as you said nothing to argue. I really want to help to figure our what is the problem. Even if 100 people has this problem, maybe we can help them and make this kernel more stable.

And if this is not absolutely kernel related (or if it is a conflict between new kernel features and an application), then again we will know about possible issues.
[Galaxy S I9000 Android Development] darckengel:
The problem is between last stable version (1.8.2d) and 1.9.0 the changes are very small. As we checked that extra memory wasn't the causr. The only kernel related features are initramfs gzip compression and usb car dock support ... (new mails patch works in 1.8.2d)
[Galaxy S I9000 Android Development] HM.Carbide:
when i flashed jvt first time, it was very unstable. I had reboots and force closes on email, phone, even in settings.

This happend on pure stock.

What i made after install was restoring data of some system apps with titanium. (email, wlan, phone, ...).

There must have been something wrong or uncompatible from my previous rom.

So i cleaned everything, and on second install i configured everything from scratch.

I tested everything for 2 days. Then i flashed Semaphore again.

Not a single problem now.

Maybe it is wrong or incompatible app data of one of the system apps?
[Galaxy S I9000 Android Development] jocke_lulle:
Just had reboots with 1.9.0beta.

Im going to flash 1.8.2d again and the screenstate-script to test it a little more to be sure that I dont have problems with that verison (my last test was ~10h but i want to test it more).

As I also restored apps and some system data (memo and messages) since my last fresh install (this saturday) maybe that can be the reason. But as everything seems to work with 1.8.2 kernel I doubt that this is the reason.

As I said im flashing 1.8.2d to test again.

Thanks all for the help and tips! I dont mean to be rude or anything when I write about my issues. If you are tired of my posts it is OK for me to use 1000mhz or go back to earlier kernel-versions for OC :) otherwise i will keep testing and share my observations:)

Thanks again!
