just a little correction :)
it was Entropy512's fix...
I just implemented it differently and then he made a better implementation.
my previous fix was a workaround and the latest one is his...
anyway. I am happy that you used that fix because that one is the biggest problem in samsung's sources.
lot's of people will be able to underclock to 800MHz without a problem now.
and that will also help me by keeping your kernel instead of cfroot in my sdcard to flash in case of an emergency :)

Yes I'm really liking the latest realease so far! Big thanks to hardcore.

I've used tegrak app to undervolt the cpu and gpu to the same settings as what the phenomenal kernel uses and everything is working a treat :)

Excuses if mentioned already but when toggling wifi off/on with wanamlite 11.1 and latest speedmod the wifi "hangs" and won't turn on. Different kernel (neak, siyah) no problem.

I know i can flash other kernel but i prefer SpeedMod cause it's the smoothest one.

    Hi guys,

    This is the SpeedMod kernel for Android ICS for the Samsung Galaxy S2 GT-I9100.

    This kernel only works with Samsung ICS based ROMs.

    SpeedMod's core features are:
    - Super stable: No undervolting, overclocking or potentially unstable modifications
    - Fast and smooth: Compiler and code optimizations
    - Excellent battery life: Remove unecessary logging and debugging

    >>> CLICK HERE for more info and the DOWNLOAD links.

    >>> CLICK HERE for the Frequently Asked Questions list.

    Current features:

    Root and CWM:
    - Automatically installs root (su) but can be disabled
    - CWM recovery 5.x

    Screen and misc tweaks:
    - init.d, TUN, CIFS, IPV6 Privacy support
    - MMC_CAP_ERASE disabled to fix the hard-brick bug (this kernel is "safe")

    Performance:
    - CPU governor tweaks: increase responsiveness
    - IO tweaks
    - Read ahead tweaks
    - Compiled with optimizations using Linaro GCC toolchain
    - Switched to SLAB instead of SLUB
    - Multi-core aware scheduler SCHED_MC

    Turned off unnecessary logging for better smoothness and efficiency:
    - Disabled Android Debug Logger / logcat
    - Disabled Samsung debug
    - Disabled various kernel debugging, statistics and tracing options

    >>> CLICK HERE for the CHANGELOG.

    Instructions on how to enable logcat and disable auto-root are in the 3rd post (below).

    >>> CLICK HERE for more info and the DOWNLOAD links.

    Here is how to change some of the kernel configurations:

    [HOW TO ENABLE LOGCAT]

    If you are a developer or want to re-enable logcat for whatever reason, do this:

    adb shell
    su
    mount -o remount,rw /system
    echo ANDROIDLOGGER >> /system/etc/tweaks.conf
    mount -o remount,ro /system

    [HOW TO DISABLE AUTO-ROOT]

    Create a file called ".noautoroot" in either /system or /data. This will disable the auto root installation. This example, shows how to remove root completely:

    adb root
    adb shell
    mount -o remount,rw /system
    rm /system/xbin/su
    rm /system/app/Superuser.apk
    rm /data/app/Superuser.apk
    touch /system/.noautoroot
    mount -o remount,ro /system
    sync
    reboot

    [HOW TO RE-ENABLE AUTO-ROOT]

    adb root
    adb shell
    mount -o remount,rw /system
    rm /system/.noautoroot
    mount -o remount,ro /system
    sync
    reboot
