Introducing my custom built kernel for ICS Touchwiz ROMs
Features:
- Built from HK ICS Update 1, and Update 3
- Very fast and very stable
- Noop scheduler as default
- SLQB heap allocator
- Filesystem I/O tweaks
- CWM 5.8.1.8 included
- Full root with SU and Superuser included from flash
- CWM SDcards are the correct way around (/sdcard = removable SD, /internal = internal 16gb memory)
- MMC_CAP_ERASE removed for safe wipes
- Speedmod patch for MDNIE (k3-7)
- Increased framebuffer and GPU memory
- Increased memory allocation for android surface pmem
- /etc/init.d/S* script support
- Lots of configuration optimisations
- Fully supports ICS 4.04 TW roms including Bluetooth
- Custom bootanimation support without the need to edit loops
EXTREME version has all the above features with the following
- Native CPU overclock to 1600mhz @ 1350mv
- Native GPU overclock to 160/400mhz @ 925/1000mv
Information
You may need to turn WiFi off then on again after flash for the module to be loaded correctly. You will only need to do this once!
If flashing the EXTREME version uninstall Tegrak or similar apps before flashing
INSTALLATION
Please make a full nandroid backup BEFORE installing either kernel. If these kernels dont work for you then you can easily restore without losing your data
Download:
Standard version
v8.1- CWM zip - http://hecubus.com/xda/kernel/GL_NOTECORE_V8-1.zip
v8.1 - ODIN tar - http://hecubus.com/xda/kernel/GL_NOTECORE_v8-1.tar
Extreme version
v8.1 EXTREME CWM zip - http://hecubus.com/xda/kernel/GL_NOTECORE_V8-1_EX.zip
v8.1 EXTREME ODIN tar - http://hecubus.com/xda/kernel/GL_NOTECORE_v8-1_EX.tar
(remember this is an overclocked kernel so it wont work for everyone - if you get no boot reboot to download mode and flash the ODIN version of the standard kernel)
INFO FOR DEVS / ROM COOKERS
If you choose to include this kernel in your ROM, please feel free to do so. however, please only include the "Standard" version to avoid the possibility that "extreme" will not work for everyone filling your threads with "my phone wont boot" etc etc.
Also, it is IMPERATIVE that you remove any reference to and / or setting of SD_CARD readahead settings from any of your tweak scripts. Setting a readahead, no matter how small or large will have a significant negative impact on the I/O throughput of this kernel

Source and GPL:
Basically i can't be bothered with GitHub so I make my entire build directory, build scripts and initramfs available in one complete package. This is compliant with the GPL licence.
There are three auto-build+zip scripts in /kernel. Take a look at them and you can figure out how to change the folder paths to your environment.

If you want to compile your own kernel using my sources, here is a rough guide for those of you well versed in linux and scripts
http://forum.xda-developers.com/show...&postcount=618
If you are building from HK ICS update 1 source (like my source) it is important that you tick "Bluetooth Mgmt" in "System Type" (using xconfig for example) to fix bluetooth in 4.0.4 roms

DISCLAIMER
By flashing any custom kernel you understand the risks involved. As with any flash, there is always a small risk that something could go wrong and/or data loss. I am in no way responsible for any damages, loss of data, brickage, loss of work or any other loss associated with any faults due to the installation of this software.
