[Q] How to revert to stock kernel w/o wiping?

I want to install Bionix 1.7 w/ JACs OC kernel. I have flashed his kernel before, but i want to know, can I flash the stock kernel and just lose my OC? In case I have to go back to stock Bionix.
So, can I expect to flash the stock kernel on top of Bionix 1.7 to get rid of JACs kernel?

I don't think this will work, I'm not 100% but since his 1.7 build is based off of the JI6, I believe the kernel is different and this might mess some stuff up for you. Please someone correct me if I'm wrong
If I decide to go back to stock, I'll have have to use odin? When I was using 1.4 w/ OC, I flashed stock kernel via clockwork. then I soft bricked :O

[Q] Flashing Kernels and Roms

I'm trying to flash a stock Rom onto my GS2 but i have a question. Does each ROM include a kernel with it or do i have flash a kernel first and then a rom? And does each kernel have certain roms that go with it or can i flash mix-and-match different kernels and roms?
Are you talking about stock roms or the modded ones in the dev section? Each rom does have a kernel that goes with it, however i wouldn't flash a 2.3.3 kernel on a 2.3.5 firmware.
In any case, the kernel has to be flashed at last, after the ROM
I'm talking about stock roms. My phone is on 2.3.4. If i flash a ROM, do i have to flash a kernel?

You can, but not every kernel supports every Rom. So I suggest make a nandroid and flash the kernel . If you face issues then restore nandroid.
I have tried many kernels on stock Rom , and never had issues till now.....
Yeah it works fine.
I don't know why you would want to stay with stock, because there are rom's like anryl's which is 99% stock, but with slight speed enhancements.

Flashing Stock Kernel

So I want to go back to stock (just been getting battery problems in MeanROM) so I downloaded the stock ROM, and the original thread said I can flash the stock kernel. What exactly would that do? And do I need to do it?
Edit: My current Kernel version is 3.08-01680 and my baseband is 1.05.11, is that the original baseband version that came out with 1.22.651.3?

The kernel or boot.img is baked into the rom .zip so just flash as normal it really only changes if you flash one by itself

[Q] Xperia P - How to choose a Kernel

While on my old Sensation, i often flashed diffrend roms, but never a Kernel that was not includet in the rom.
From what i have read in this forum, youd could increase the batterie time, if a custom kernel is flashed.
The tutorials for flashing a kernel are well writen, so i don't see a problem here. And yes, i am aware, that i nee to unlook the bootloader to flash a custom kernel.
My question is, how to chose a kernel? For what information do i have to look?
And for understanding. Do i have to flash another rom to get a custom kernel running, or could i stay on the stock rom and try the kernel itself?
Does a custom Kernel mean, i loose some of the functions that are in the stock kernel /rom or do have all kernel the"basic" functions of the stock kernel and just have addional functions and optimization?
Thanks for your time and help.

You don't need to flash custom kernel to increase battery life.
All you need to flash a custom kernel is unlocked bootloadr. Be sure to save DRM keys if bravia engine is important to you.
Then look for a custom kernel for stock roms, and custom stock tom too if you wish, or you can choose a non-stock based rom abd kernel.
