I think i'm suffering the same problem, but I could add: every time an application try to make any system change, phone reboots. It happened to me a lot of times with several applications like appearing or busybox, for example.
But every application I used was tested before in the same phone with KPU and VurrutKer with no problems until now.
Maybe this is the reason I can't install busybox now on this phone.

I don't know, but I had this problem since the first version of gingerbread, so I don't think it's related to the value pack

I remember having this problem when CF-root was installed. It doesn't happen to me on my rooted stock install. Could be some permission or a mount option.
I will look into this, but am currently very busy. As this may take some time, I can only recommend to try another busybox installer from the market...
today after i finished a call i faced an FC when trying to end the call hmm dont know why.. any idea ? i flashed yesterday this : 1 % Battery + Ics Animation - used UOT Kitchen. bam kernel stock ddlf2!
Don't worry because it's not a big problem by now. I tried 2 different installers with no exit at all. Installed this stock rom (xxle4) twice with your kernel with the same result. So, take your time, receive my thanks but, please, don't forget to take a look at this issue ;-)

Thanks bro
I updated Superuser from the play store sometime back.. now none of the apps have root access, it says "superuser access given" but it actually doesn't..
tried to update the superuser binary, again failed..
Tried flashing bck 14 fix again and the issue still persists..
Anybody with a solution to this ???.
DDLF2 , Bck v14 fix, sio, smartassV2.
min 300, max 1000.

I did think of that, but the superuser app is a little more complicated than others.. so I don't want that to make it worse..
EDIT : It worked, all's fine now.. thanks.

@xdabam HW decoder is a bit unstable,it sometimes hangs and this is on normal avi vids,i have tried the cf root of Ganesh ,the hw decoder works much better on that kernel.
More info please:
- Which ROM are you using?
- Have you flashed the kernel on a clean stock ROM?
- Does the phone hang or only the player?
- Are you running @ 1.2 GHz when using BCK (as far as I remember, ganesh's CF-root does not include overclock)?
- Do these problems also happen with different governors / IO schedulers?
- Did these problems occur on BCK beta 13?

Sorry for not giving the info
1-Im on DDLF2 Stock.
2-Yes.
3-The player hangs,but audio still plays.
4-No ,i was running the default frequency,which was 1 ghz,i have also tested it on 1.2 ghz,same problem.
5-Yes
6-i cant test it since it might break the wifi.

Well lucky for me i'm not experiencing any of that issues even if im still in XXKPN deodexed. By the way, you should try governor smartassv2 and io sio. I use stock video player and mx player without any hangs. Just few split second lags but not a big deal. And for avi vids, no lags or hangs at all, i just watched sherlock holmes the game of shadows nonstop using my phone, enjoyed it.
maybe you can try to flash the firmware again if it is not too much bothersome to you, that's what i did when i actually soft bricked my phone by transferring some egl driver from cm9 to gb (stupid decision ). I recommend it in a clean firmware or use the kernel cleaning script, forgot where it was but you can just search it and apply the most compatible script for our device.

Thanks for the info. That's rather odd. Please try if it happens on other players and files, too.
I just tested it on my phone running XXLE4 with beta 14 and there were no problems playing a movie for half an hour each on 1 GHz and 1.2 GHz

hi there XDA_BAM
can you help me port your sync fix to the galaxy note N7000 kernel?
i am new to building kernels but i was able to build kernel and tested it on my device and it was working but i want to add this feature because i have problem with whatsapp and email sync which arrives 10 to 30 minutes late
thank you for your hard work

Are you sure that your problem is related to ours? Because I have never seen such a f***** up implentation of phone_SVN like on the i9003 on any other Samsung device
Anyway, this commit solved most problems on the i9003. Feel free to adapt it to your needs.

126BCK - Bam Custom Kernel for i9003 / Galaxy SL
This Kernel is based on the Chinese GB source, released by Samsung on the 18th of November. Last changes to the source were made by Samsung on November 15th. If you still have questions after reading this post, look at the FAQs (including a list of requested features and known issues).
Kernel features:
- No SOD
- Bugfixes:
~ Sync bug fixed. Notifications for new mails and messages should arrive within one minute under all circumstances
~ Bluetooth problems fixed. Your phone now should play nice with bluetooth hosts, i.e. your car audio system
~ Micro stutters nearly completely gone thanks to lowered processor transition latency. It's smooooooooth
~ Home button double presses exterminated - Governors:
~ smartassV2 governor by erasmux (default)
~ interactive governor by Mike Chan - IO scheduler:
~ SIO IO scheduler by Miguel Boton (default)
~ BFQ IO scheduler by Paolo Valente and Fabio Checconi
~ deadline IO scheduler - Extended features:
~ ro.secure=0 (root acces through adb shell - to root the 'clean flavour' of BCK, please follow the instructions)
~ EXT4 support (to convert your file system, use amit.bagaria's ext4 add-on .apk) (Only in CF-Root .tar)
~ Support for init.d scripts (to use scripts, please follow the instructions) (Only in CF-Root .tar)
~ BLN support (to use BLN, please follow the instructions)
~ TUN support for VPN networks built-in (no module needed)
~ Increased SD-card read ahead of 768 kb for improved read speed
~ Available with universal CF-root ramdisk based on amit.bagaria's version, improved by loSconosciuto (Only in CF-Root .tar)
~ Available with universal CWM ramdisk (rooted) based on universal CF-root, but 'tweakless' (Only in CWM .tar) - Overclocking and Voltage:
~ Evolved sysfs interface for variable overclock or underclock (all operating points [OPPs] can be adjusted seperately)
~ Fifth OPP (1.2 GHz) available, device booting up at stock speed (1 GHz)
~ Total frequency control. The device will never run at higher speeds than defined by you, not even on WiFi.
~ sysfs interface for voltages (read only at the moment)
~ Slight undervolt (3%) on all OPPs
Flashing , settings and compatibility:
If you want to use BCK, please flash it on a clean stock ROM. If you want to go back to stock, repartition and reflash the full firmware with ODIN. This kernel will not work on CM or MIUI.
The CF-root and CWM versions (PDA_BCK_CF-root_universal_***.tar / PDA_BCK_CWM_universal_***.tar) can be flashed on any recent Gingerbread firmware. These versions are pre-rooted, which means they include Superuser.
The non-CF-root "clean" version (PDA_BCK_XXKPQ_***.tar / PDA_BCK_XXLE4_***.tar) will only work on XXKPQ / XXLE4. Do not flash this version on anything other ROM than the one indicated in the file name. This will break your WiFi. It's especially risky to flash the clean version of BCK after flashing any CF-root kernel before. Don't do it. This version does not include Superuser, but it is prepared to be rooted. Follow the instructions to do this.
After a kernel update, please wait for the device to boot up and reboot once. There is generally no need for cache cleaning or a full reset. To change the governor and IO scheduler, I use NoFrills CPU Control from the market. It's free and reliable.
I recommend to use the clean XXKPQ version. If you want / need to have root, try the CWM version. If you want the 'full package' with FuGu-Mod and more, use the CF-root. I recommend that you do not apply any further tweaks and use a stock ROM.
>>> Warning: Overclocking may damage your device. <<<
Overclocking instructions:
For overclocking, you will need a shell on your phone, or adb access. I use Android Terminal Emulator. Overclocking is currently limited to certain frequencies (see below) and all operationg points will be set with the stock voltage of the corresponding stock frequency. The frequencies you set have to be within the following ranges:
Remember that your phone uses all operating points depending on the current load. Anything more than 10% higher than the highest stock frequency is likely to be unstable, but you are free to try it. To change the clocks, open Terminal Emulator (or type 'adb shell') and hack inCode:OPP1: 100 - 500 MHz, stock 300 MHz OPP2: 501 - 700 MHz, stock 600 MHz OPP3: 701 - 900 MHz, stock 800 MHz OPP4: 901 - 1100 MHz, stock 1000 MHz OPP5: 1101 - 1500 MHz, stock 1200 MHz, not used by default
as an example. The others are opp5, opp3, opp2 and opp1. That's it.Code:su echo "1100" > /sys/power/overclock_opp4
Settings will be lost at reboot, unless you add them to your init.d scripts. I do not recommend this, as this may cause boot loops if the settings are to high! Be advised that NoFrills CPU Control, SetCPU, or whatever app you use that may adjust clock settings interfers with this. You may wanna update their settings after this. I do not recommend using them to set anything at boot if you overclock any OPP, because they might save the wrong frequencies and crash or do worse.

MD5 sum:
26UPDATE: BCK beta15 is up. This version is mostly identical to beta15rc8, but is compiled with the user_defconfig. That means there is less debug stuff in there than in the rc releases. Go for it!
On a side note, this may very well be my final release. I've had very little time these past months to maintain the kernel. I know there are some annoying bugs left, but I currently do not know how to fix them and probably won't have the time to learn how to. Therefore, I can only encourage everybody to try it themselves! My full sources are on Github and since this is open source, everybody is free to join or take over the development
It was always a pleasure sharing with you. Stay positive
Changelog:
beta 15:
- Universal CF-Root: Modified some permissions to bring it closer to the stock ramdisk
- Universal CWM: Created a CWM ramdisk based on CF-root, without most tweaks. You now have three BCK flavours to choose from
- Updated to newest UPDATE2 sources by Samsung
- Sync bug fix reworked to use new Samsung method from UPDATE2. This may lead to slightly lower standby battery consumption.
- Fixed accidental front camera mirroring
- Editing smartassV2 settings with busybox 1.20.x and newer no longer leads to reboots. Thanks to loSconosciuto for pointing me to the patch.
- Fixed complete crash of WiFi driver when activating WiFi by adapting smartassv2 thresholds
- Reverted to the original Google Android toolchain using gcc 4.4.3
- Because of the toolchain-switch, the compiler optimizations are now back to -O2 instead of -O3
18UPDATE: Beta 13 is up. There are some huge improvements to the user experience in this one, and - also thanks to loSconosciuto's help - some rather annoying bugs are gone. Test it - you won't regret it!
If there are no major issues with this release, the next one's gonna be 1.00.
Changelog:
beta 13:
- Updated sources to GT-I9003_SWA_GB_Opensource_Update1 from the 30th of March
- Universal CF-Root: Backup is not failing anymore when started from CWM. Thanks to loSconosciuto.
- Universal CF-Root: Some small improvements to multiple scripts.
- Home button double press issue fixed. There should be no more unwanted double selections in CWM and you can now reliably long press the home button to bring up the list of previously used apps. Idea and timer function taken from a patch by Tegrak.
- Fixed priority class for CONTENT_PROVIDER not being set, which may have caused apps of this class to be ignored by the autokiller, resulting in less free RAM.
- Lowered OMAP processor transition latency to the value recommended by TI. Subjectively, this brought huge improvements in terms of reducing micro stutters.
- Lowered CFS scheduler latency and granularity to values very close to mainline kernel defaults. This could reduce lags in some critical situations, but it doesn't do wonders.
- Switched to SIO as default IO scheduler.
17UPDATE: beta 14 is up! For everybody using the ValuePack (XXLE4): The CF-root version of BCK will now root your device without breaking the WiFi. For everybody else, I recommend that you read the changelog and update as soon as you're comfortable
Changelog:
beta 14:
- Universal CF-Root: Replaced CWMManager and TweakManager with zipaligned files. Thanks to loSconosciuto.
- Universal CF-Root: The TweakManager is not replaced on install if it didn't change to preserve it's settings. Thanks to loSconosciuto.
- Universal CF-Root: Corrected problems because of too little free space in /system when converting to ext4 by permanently moving InfoAlarm.apk from /system/app to /data/app. Thanks to loSconosciuto.
- Universal CF-Root: Fixed the non-working WiFi on XXLE4 and prevented future problems. Instead of patching the WiFi modules, they are now replaced. Thanks to loSconosciuto.
- Universal CF-Root: Fixed some small mistakes in the CF-root install procedure.
- Switched the compression of ramdisk and kernel from gzip to lzma. This makes the files much smaller and allows us to include more 'stuff'.
- Changed smartassV2 settings to wake up at lower frequencies. Further, it is not locked at 300 MHz anymore when the screen is off. Tests showed that free scaling is more battery friendly.
- Removed InteractiveX and OndemandX governors and added the Interactive governor by Mike Chan (Source: CyanogenMod Crespo kernel). Since free scaling proved to be more battery friendly, the screen off profiles in InteractiveX and OndemandX made them superfluous.
- The device will not scale above 1 GHz for some seconds when booting anymore. It's now safe to use BCK even if your device can't handle 1.2 GHz. Based on a patch by dalingrin.
- Changes in PM to respect cpufreq policy limits when playing or recording video. The device should respect your wishes under all circumstances, now
- Fixed the SmartReflex voltage calibration of the OMAP SoC for OPP5. This could lower power consumption as soon as OPP5 (1.2 GHz) is activated for the first time.
- Slight increase in the OPP5 nominal voltage (1.40 V -> 1.42 V) to allow for some adjustment by SmartReflex (now that it's working...), if necessary. The actual voltage when the device is running will not change for most users! Based on patches by dalingrin and Sanjeev Premi.
Code:stock BCK OPP5: not def. 1.4200 V
PS: If you're missing Lionheart or Lulzactive, look into the FAQ.16UPDATE: Please feel free to test BCK beta 15rc7 in the Universal CF-root flavour or with Universal CWM. I recommend that you flash the flavour you have currently installed (i.e. use CF-root if you currently use CF-root). There are only very small changes compared to beta 15rc6 and so far, no serious problems have been reported with the latter release. A backup is recommended none the less. I hope to have fixed most WiFi problems with this rc, although it might still hang from time to time when acquiring an IP address.
Let me know if this release solves the WiFi problem for you (and if you had it before)
Changelog:
- Possibly fixed complete crash of WiFi driver when activating WiFi
- No SOD
