@ voit & Unkalo: Can you be more specific?
- What setup do you have? Are you using a custom ROM?
- When does the phone freeze? Immediately after turning on WiFi or after some time?
- Does it always freeze, or only when restricting frequencies?
Yeah thats rite, flash as PDA..Also can use mobile odin
Tested it and this kernel is totally awesome, i like the way its restricted the CPU frequency. Never jump beyond what we set earlier especially on Wifi. Perhaps it will give more batt life
No crash until now n additional gov would be more awesome.
Thanks BAM
Edit: tested many diff frequency on OPP5 and found my phone cant OC above 1170Mhz, so sad but that explained why my phone cant boot on Vurrut v2/v3 on CM7/MIUI kernel

Changelog:
beta 9fix:
- Reverted: Changes to OPP switching code. May lead to less 'hickups'. (Patch caused random freezes using WiFi.)
- Reverted: Bugfix for framebuffer code. (Patch showed no noticeable benefits.)
Then i just nid to flash it rite? no nid wipe cache/ partition and factory reset?Yeah thats rite, flash as PDA..Also can use mobile odin

no more other work?
like install some CPU Frenquen apps?

The standard procedure after flashing new kernel/rom, u must wipe cache, dalvik n batt stat
Only if u have probs after boot like apps FC, pliz go for factory reset.
Just installed cpuspy n no-frill cpu control. Terminal emulator /ADB is needed to alter custom freq. See the OP for info.
Thats all n pliz correct me if im wrong

I am using a stock rom.
Frezee after some time (variable) switch on wifi.
Frew are 300/1200, i am not remember if i am using bfq, or deadline.
Now using 300/1000 smartassv2 and bfq and no frezee.
my bad, i dont see the v9 fix,

Sorry to post this here.... but if the pushmail issue is framework related then maybe it can be solved by replacing the concerned files from froyo or i9000 gb rom.... Can anyone please try that... I can't right now...

REQUEST: I am still investigating the sync bug. It would be very helpful if someone who is running a Froyo stock ROM could drop me a dmesg. To do so, please reboot and let the device sleep for about one hour. Then go into Terminal Emulator and type
After this, please post the file as an attachment in this thread or use pastebin and post the link. Thanks!
Code:
cd sdcard
dmesg > dmesg_froyo.txt
@XDA_Bam
Attached is the dmesg that you have requested. I might be running stock Froyo for a while so if you want anything else just ask me, I will try to help
*info - I let the device sleep for about ~40 minutes before I took the dmesg. I have made two of them, the first without the data switched on and the second the data is turned on (2g) (don't really know whether it has any difference).
Hope it will helps!
edit - now that I have remembered, I might forgot to reboot on the dmesg that have the data turned on, so if you want, I will make a new one later.

I'm very glad for this.
This weekend will be for me a 'flash weekend' because I have planned to make some test on my phone with MIUI and CM looking for backlight issue, if you need other data from Froyo I can also flash it to provide you the dmesg. Tell me if you need it.
@xdabam I been using v8 it works very nicely, but v9 fix, gives jerks and lags a little, can you add the frequency bins(120 MHz) that vurrut has added, with that patch of Wi-Fi and uv this kernel will be the best

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
