What is it?
This is a kernel I have been working on for fun when I have time. Is uses some commits from Daz and his ICS/JB kernel, Quite a few commits from Code Aurora Forum and a bit from Omegamoon and Geno. I have Also recycled some code from my previous 308 kernel for the Huawei X5/u8800.
I used the 3.08 kernel source from Huawei as a base and pulled the boot.img and config from my stock b936 vodafone NZ rom.

19/01/13 update:
I broke my build environment a while ago, and my last kernel stopped building. Have finally rebuilt environment again properly and I decided to use Genokolars kernel as a base to save some time. It helps that his source is nice and clean too and he has documented his changes well. His source is here:
https://github.com/g...kernel_msm7227a

This Kernel is for stock/stock based roms only. It will not work with CM9 or CM10.

What does it have?
Old Kernel

Spoiler

First Release #16:
Overclocking, which I don't use and have not tested.
Lots of KGSL (graphics) fixes
Updated touchscreen drivers thanks to Dazzozo and Fagulhas
Tweaked SIO and stock VR ioscheds, I use SIO
Tuned Smartass2 and stock InteractiveX governers, I have customised smartass2 the way I like it.
Bluetooth BNEP enabled, Stil not one hundred percent sure about this one, seems to be about bluetooth networking.
Some small CAF audio changes.
Updated lowmemorykiller values set in the kernel.
A CAF battery calibration fix, you may experience a battery drop while this calibrates, but after a charge/discharge/charge cycle this is fine and I get through a full day with 60% left in the battery.

11/11/12 Release #19:
Init.d support from Cyda- need to know if this works, I don't use init.d scripts myself.
Some Governor tuning in interactiveX and conservative governors
Zram enabled
Dazzozo's fix for wifi crashing and deadlock from CAF

Current Kernel:

Spoiler

19/01/13 Release #6:
New kernel based of Geno's source.
Has Ramdisk from B952 stockplus.
Largely the same tweaks as before, but with some left out that I felt caused instabitity.
Seems to be about the same speed wise.
Looking to put some more changes in and hopefully fix zram eventually.
Includes the init from Unaszplodrmann.

19/01/13 Release #7
Removed the modified init, seems to cause some phone weirdness.
Set smartass2 as default governor.
Added more entropy into the kernel. I doubt it does anything, but why not. A bit more randomness to pull from can't hurt, can it?
Added updated zram and turned on in the defconfig

21/01/13 Release #11
Added Lagfree Governor
Added Wheatley Governer

23/01/13 Release #12
Made smartass2 a bit more responsive
Updated Freq's from CM9. 1.19ghz back, 1,3ghz gone because nobody can use it.

28/01/13 Release #13
Added swap
small memory management fix
turned off some huawei logging

03/02/13 Release #14
Goodbye Wheatley, wish you worked better on our phone.

07/02/13 Release #15
Really goodbye Wheatley, you stuck around like a bad rash.
Made working directory clean and did a full clean build.
Probably final unless some really cool stuff comes along to try.

Disclaimer stuff:
I have tested this as working on my phone, I am not responsible for fires, death or nuclear war breaking out if you use this kernel. I have only tested it using the stock+ B952 rom, but it should work on all stock based roms.

#16 update kernel: http://www.mediafire...7444bntbq0aqmi4
#19 update kernel: http://www.mediafire...3d0irtycdyybw7x

Current Kernel:
#6 update kernel: http://www.mediafire...94uuu9ebcxyts7a
#7 update kernel: http://www.mediafire...5f9947r4hxurklj
#11 update kernel: http://www.mediafire...guspai8u69i29sn
#12 update kernel: http://www.mediafire...sej3w8ipxo7a16r
#13 update kernel: http://www.mediafire...43116mf34ttvs5l
#14 update kernel: http://www.mediafire...ap4glxz57tp9zjm
#15 update kernel: http://www.mediafire...j19164hvx2z8956

Higher number is the latest and is highlighted above. If you look in Settings>about>kernel Version, you should see it match the kernel number there. You can flash your kernel/rom of choice to get back to your previous kernel. #15 looks to be final unless something really cool kernel wise comes along.

Just come back to using my phone for the first time in a while and realised that it was a bit choppy. Not sure why I didn't notice it before. Anyway, have set the governor values back closer to stock and added some small changes like updating SIO and changing the lowmemorykiller values a little bit. Seems smoother so that is cool.

I use ubuntu 12.04 LTS and build off the u8815_defconfig.

Sure, here you go, its a kernel... Sorry man, its not a rom, so there is not much to take a picture of.

Is screen more responsive now with this updated touchscreen drivers?

[TangerineTractor]

Just added this to Stock+944, using the overclocking settings recemmeded in Stock+, and it's made it even nippier! No issues at all, and the phone is now running very fast. My rule of thumb benchmark is how long it takes to open Opera Mini from closed... Infusion about 5 secs, Stock+ and JellyCream are both about 4, Stock+ with this added is less than 4.

What's the touch screen like now

absolutely fine, but then again I never really had any issues before.

[KaterM]

absolutely marvellous!
Congrats & thx for sharing
will have a look at your changes in detail.
luv the kernel pic!
always pictured it as the inside of a walnut crossbred with Jonny Mnemonic xD
@T.Tractor: might try this combo on top of my B926. Sounds good!

[Cyda]

Sounds great, I've give this a blast. Thanks a lot.

[TangerineTractor]

Been working fine so far... but I just had a missed call and eventually got a hang from the phone process... I used to get this occasionally on other roms, so I don;t think it's particularly this kernel or anything though... might be more to do with running exdialer and the missed call not being cleared properly.

[michal.siman]

I just install it, and with first minute, i feel diferent with reaction on touch. My first verdict is: this kernel i looks very good.

[Cyda]

Any chance of init.d support and adding 122Mhz to the frequency options? I think with those two extras this would be my new kernel of choice.

[Geoff2]

I like the sound of this, but I've never installed a custom kernel before.  Do I simply put the zip on my SD card and install it from ClockworkMod - i.e the same as installing a custom ROM?  Any specific wipes/formats you'd recommend?

[Frankish]

Install through clockworkmod with no wipes. That's all.

Nice one - thanks.

[thejaimes111]

Awesome, thanks for this new kernel
Going to test

[nsmacd1]

Any tips on an overclock program, and settings which won't crash the phone? - Thanks!
