I have flashed Roms and Radios, but have not yet flashed a Kernel. Does this mean that my T-Bolt is using the stock Froyo Kernel, or was the Kernel replaced each time I flashed a Rom? Thanks in advance for your replies!
Each ROM comes with it's own kernel. Usually the one it comes with is the best fit but not necessarily. Not all kernels will work with every ROM. See your favorite ROM's thread to find out about kernel compatibility.

Thanks for helping me to better understand this!
If you're using gingerbread, there's only 2 kernels available for flashing. Imoseyon's, and Dreamkernel. Most will use one of these two. Synergy and Gingeritus3D use Ziggy's, which are generally custom built for the ROM and are the only kernels that will be fully functional with these ROMs. It is possible to extract the kernels from one of these ROMs and use it with another, but you will have issues with it. Unfortunately, Imoseyon hasn't been terribly up to date with his kernel, which is the source for dreamkernel and Ziggy's. Ziggy has been building kernels for years now and has kernels out for 4 or 5 devices and currently has the only custom kernels that are fully functional with the latest GB leak. I've toyed around with extracting it from Gingeritus3D Beta6, but frankly, I don't have the time or interest since Chingy's ROMs have been my daily drivers for about 2 years now. I do have an older Ziggy kernel that was extracted, and if you want to play with it, I can send you a download link.

Good point. Too bad AOSP makes me wanna bore holes in my head. Every time I pick up a phone with AOSP on it its set up different and works different! ...but its what the girlfriend likes so I flash the crap and walk away. I really need to get her doing it herself!

I'm simply wondering if kernels in gingerbread ROMs would be interchangeable with kernels for froyo, assuming sense is considered. I really don't want to spend all the time to flash a new radio and ROM just to find my kernel won't work.

Roms include kenels so whatever kernel the Rom comes with is what you'll have until you flash a new kernel after you've flashed the Rom.
So I recently flashed the OTA Rom and I noticed I can't overclock it, is there something I can do? Do I need to flash a kernel or something, also is it possible to change the top bar because I don't like the stock version, like change the theme but I don't want to change the launcher at the bottom . Sorry for the noob questions lol
Best advice would be to flash this ROM. http://forum.xda-developers.com/showthread.php?t=1227075 Droidth3ory makes awesome roms. This rom is based off the latest GB build as well. It also will include a kernel for overclocking into it. Also, he has an app called the "Candy Stor3" in his rom, which has theming options to it, if you want to change how your phone looks.
To answer your question though, with OTA roms, there aren't custom kernels loaded into the rom, because OTA roms are what is "out of box" state. It will come with the manufacturers kernel. Even though the version GB version is updated, I believe a Sense kernel should work with your rom.
Awesome, thank you so much
I put together a rom based on theory's rom listed above, then flashed a sense kernel for overclocking, n it seems to break wifi. So I'm not sure if u can o/c the new 2.10 base yet, may need a new kernel

You obviously tried dreamkernel. Imoseyon has the WiFi fixed. Neither have been at all diligent about keeping their kernels current so there are basically no custom kernels that are fully functional with any ROM base newer than 2.07. The lone exception would be Ziggy's, but you'd have to strip that out of Gingeritis or synergy.
Hey everyone, this is thread is meant to centralize all of the information and questions about the kernels for this phone. I feel as though information about peoples issues, and their "triumphs" with certain kernels are scattered everywhere, so finding useful information can be tedious. I have noticed that most, if not all of the ROM threads specifically say, "No kernel questions". This is what this thread is going to be for. I also thought it would be neat to have some general discussion about kernels. for example, what kernels work best with what ROM, what are some of the issues that people run into, what works, what doesn't work, etc...
I know there is only a few kernel options now, but hopefully that list will grow and as it grows this thread will be become more useful.
there are only a few rules for this thread:
1. No flaming-one of goals for this thread is to help noobs, this thread is meant to de-clutter the ROM threads of kernel questions, (seemingly stupid or intelligent).
2. This thread is for talk of kernels only, there is a "off topic" discussion thread for everything else; and ROM threads to specifically talk about ROMS
So far i only know of three kernel types:
Faux's kernel
Stock kernels
X boarder's kernels, (different variants to go with different ROMS).
From what i understand Faux's kernels work with pretty much all of the ROM's but seem to cause boot loops.
I do not know too much about X's kernels and the issues they cause, so it would be nice if some one filled me in.
Ill start the thread by saying, I have used the stock kernel that shipped with my phone over the quick sense ROM, and the Bullet proof 2.4 ROM. the weird thing with that was, my WIFI worked. its weird because X, and everyone else says to flash one of X's or Faux's kernels or else wifi will not work. I have been apprehensive about flashing kernels because of the boot loop issues people have reportedly been having. however i went ahead and flashed the kernel that was included in the Bullet proof 2.4 ROM. i haven't used the phone all that much so no bootloop yet. the phone is fast and smooth. X's kernels are able to be overclocked and have three governors. i am very curious about Faux's kernel because he did some amazing things on the Mytouch 4g when i had it.

so ur sayin we can flash most of these roms & still have the stock htc kernel wrking but wifi might break? so how about NRG's modified stock kernel on the Energy rom,will it wrk on all amaze roms & will wifi not break?? im coming frm a mytouch 4g so this phne is a lil complicated..sorry for actin like a noob lol..i havent used that easy kernel flasher,i been using flash image gui & heard that fauxs new kernels cnt b flashed with it?

Idk about the WiFi question, I'm not educated enough on that, but what I've found to be successful is flashing the boot.img from xboarders ROM's .zip file with easy kernel flasher to get the best results. But with Energy ROM, I flash the stock kernel he provided with the stock kernel flasher. That method has worked flawlessly for me. I've never had a random reboot and I've never had a broken WiFi or BT. I've never had to flash a kernel more than once due to failed flash either.

Thanks for the response.. i just wanted to read up on all this more before i flash another rom..Ive been on Energy rom since i got the phone but at first i had the wifi issue,then i went & dwnloaded his stock kernel & flashed it thru flash image gui..i dnt have access to a computer unless i go to a friend house so i rely alot on flash image gui lol.. thats why im askin if its fine to flash roms without flashin another kernel..
I'm not sure why, but the stock kernel worked just fine On quick sense and on bullet proof. I never had a wifi issues on those but the wifi on the energy rom didn't work. I'm using faux's kernel on bullet proof 2.4. I guess fauxs kernel is included in the bullet proof zip. I have only had 1 reboot in the past week. Also faux's kernel can be over clocked which is nice if your into that. I came from a mytouch 4g also so learning all this stuff can be a pain but once you read over everything its really not that difficult

I finally relocked and forced the RUU (newest official version of our phone software) which puts you on the stock everything (ie kernel), and am running just fine on Energy ROM. Wifi works great, I haven't tried Bluetooth. So a far as I can tell, the stock kernel from TMo RUU 1.43 runs great and wifi is perfect. FYI.

I bet most of the kernel issues in this thread would be from people having issues with flash image GUI. Not a fact, just a strong uneducated hunch

2 kernels that im aware of is flashable with flash image gui,the amaze stock kernel frm Energy rom & the faux kernel frm fast amaze rom before the new update i guess.. Other than those 2 kernels i heard EKF modules or something like that cnt b used with flash image gui.. People gotta read before flashin things lol

I'm probably just educated enough to be way off-base, but it seems to me a kernel with a wifi problem would also have a BT problem. Do people tend to experience those 2 together?

I'm pretty sure it had to do with the official build each rom is based off of. I know the official update to 1.43 changed the kernel around so if people have a stock kernel from an earlier official ruu the wifi and bt break when updating to a build based off 1.43. Most all roms past xboarders beast mod 2.0 are built off 1.43 at least. I think there are some ones newer than 1.43 but I'm not sure if the kernel had any updates in those builds.

I am trying to figure out which of the Entropy's Daily Driver's is the best non-buggy to use or...
suggest a different kernel, I really don't feel like flashing 10-15-20 kernels to find the one that is most stable and most reliable with the goodies required
Depends on which firmware you're on...
Stock based Gingerbread I suggest the latest 3/7 DD from his thread... or Siyah kernel
Stock CM7 Kernel for CM7 (as it already comes with all his additions) ...or Siyah kernel
His ICS kernel is only for certain i9100 roms...
and the CM9/AOKP stock kernel should be used if using CM9/AOKP according to the big man himself. (again, him and the CM9 team share code...) (there's also a kernel by Fenny for ICS roms being released soon) ALSO- Siyah Kernel will be updated in short order for ICS/CM9/AOKP...
But definitely the latest daily driver or Siyah kernel if you're using Gingerbread (and soon ICS)...
Entropy and Siyah used to be very different... but most features match these days in the gingerbread versions- as I'm sure they will in the ICS versions.
And if you're running CM9 or AOKP, use the kernel they come with to avoid malfunctions.

Read the DD thread and make your own judgement - but you're still going to end up trying 3 or 4 minimum if you really want to get the "best non-buggy" for your use. Results varied across the board for everyone who tried the different versions. And 15 minutes of your time reading would probably cross 80% of them off your list of ones to try.
Stuff after 12/8 seemed to not play well with AT&T's broken bases (UC anything).
If you're on a base that doesn't suck - go for the latest on GB.

You don't want to flash them to find out which works best for you?
If I was to install, say, the Liquid Smooth ROM onto my i717 (I have a good amount of experience with flashing ROMs, so that much I know,) specifically, the KitKat version, it lists kernels in the download links. Would these kernels be included with the ROM files themselves, i.e. install at the same time as the ROM, or would I have to flash the kernel separately before flashing the ROM? Thank you VERY much in advance

The thread should tell you if the kernel is baked into the Rom our not but the stock kernel usually comes with it. I'm pretty sure you're talking about a beefed up kernel tho. You'll just have to read the thread and if you're still not clear about it, ask in that thread to be sure.

there is always a kernel included with a rom. most alternate kernels are made and or flashed to combat a side effect or incompatibility with some folks devices. its not that provided kernel doesn't work, just that every device is different and the alternates can sometimes be more compatible.
however, I would suggest you give the original kernel a chance to settle, at least a day if not two. if it just flat out is not working for you, then flash an alternate onto the rom. wipe you caches ( not factory) flash kernel by itself and your good
never want to discount reading here as Gimmeitorilltell suggests. reading educates you and puts you in a better position to help yourself first.

In general stick with the kernel that comes with a ROM unless you have a reason to change, like stability, overclocking, etc... but you do flash the kernel after the ROM; anytime after the ROM flash really. You don't need a clean flash before kernel switch.
The dev probably did not test his/her ROM with every kernel possible so if you want support your best bet is to be on the kernel included. For the 1st install of a ROM if you are unsure you should definitely use included kernel; as sometimes you just can't predict what changing it will do.
That said there many of us do switch kernels when installing updates, I certainly do. There are not alot of kernels for our phones as only a dedicated few devs continue to support the Note but you have a few choices. All kernels I've seen allow performance/governor control to some degree. If you read through the various ROM threads you'll find that some kernels are preferred by users but for the most part kernels like Uber work well with most ROMs.
P0llution's ROM patch allows you to switch kernels after flashing a ROM (BeanStalk, LiquidSmooth, etc....) and even before 1st boot. It also has patches for various KK problems. It is in the Beanstalk thread 1st post.
Thank you so much for your replies! Installed LS and flashed Uber kernel and running with no issues.
