He is not saying that it will not work on other ROMs. The kernel is just not supported, meaning try at your own risk. If you are having any issues with his kernel in another ROM then don't come into this thread asking for help. He will support it on things he knows will work, and if they do not then he will fix it. There are just so many variables and tweaks going on in different builds, impossible to support all of them.

[Vibrant Android Development] jcc332006:
Agreed. Im on axura 2.05 using aoverkill 1.3 and my phone is freaking flying with decent battery life as well. Minimum quadrant 2200. If I look at my phone it starts working without me touching it. Lol!:D

Sorry but which kernel? Thanks
[Vibrant Android Development] player4lifeov:
It was using Eugene's A5 kernel with the latest 2.2 Froyo update that has to be flashed through Odin. I will admit though, I haven't able to reproduce this score :-(
[Vibrant Android Development] msnuser111:
I tried flashing the newest kernel,B_1120_100,and for some reason it kernel panics if I try to charge with the phone off.It is fine with the phone on,but it shows an android logo in the top left corner with red text over it,and the right side says kernel panic. It is great when the phone is on though,and same with my usb cable,it only kernel panics with the phone off and plugged into my wall charger. I'm running Auxora 2.0.5.
[Vibrant Android Development] RensoreK:
same issue. Didnt happen wirh 2.0.4 ...
[Vibrant Android Development] msnuser111:
the exact thing it says is:

RST_STAT =0x4

PWIC_IRQ1 =0xc0

PWIC_IRQ2 =0x0

PWIC_IRQ3 =0x0

PWIC_IRQ4 =0x0

PWIC_STATUS1 =0x0

PWIC_STATUS2 =0x0

^that is in red text over an android logo and next to it,it says "kernel panic Upload mode" in yellow letters,with the red text covering the K and U in Kernel and Upload. holding volume buttons and power or battery pull both make it reboot,and it boots fine.

How is battery on a12?
[Vibrant Android Development] jumaaneface:
thanks for the response. I believe i had most set for -50 to -100 and the kernel paniced when aim when into a forceclose boot loop. But i shall try these settings. Your input is appreciated.

without conditioning my battery, flashed over jk2 odin and for 50% i got about 4 or 5 hours of nonstop use trying to deplete battery, meaning screen never got the chance to sleep and hace it oced
[Vibrant Android Development] mpena0689:
What about the scheduler?
[Vibrant Android Development] qreffie:
And we're back!

Still not 100% clear on what the hell I did that bricked it, but after a bit of panic with Odin not working (got it to finally flash me back to stock on the 4th or 5th try) I was able to reflash R12 and A12, and install the No RFS JFS lagfix. Let's see how this'll work out...

[Vibrant Android Development] simpsons345:
so you flashed over r12 kernal with jk2 odin kernal?? my battery sucks with default r12 kernal :confused:, could you tell me how i could flash over jk2 kernal cause im a noob at these kinds of things :rolleyes:
[Vibrant Android Development] ellopr:
Having the same problem. If we can't get to recovery, how we going to flash the new kernel to fix this problem?? I guess odin.

By the way thanks Eugene for all this. I don't mind having problems case you always come through and fix it.
[Vibrant Android Development] eugene373:
To get into recovery you Pull the Battery & Hold both Volume Key with the Power Button while you Put the battery back in... When it switches from Vibrant to I9000 let go of the Power Button while still hold the volume buttons..

@Everyone Else

~~~ Going to spend the Rest of the Weekend Optimizing the Kernel for Battery Life, Like the way I did on Kernel #45

Once that's done then the last thing to be done is finding the Hex location in the source that triggers the boot screen ( I9000 / Vibrant / ATT ) Logo's..

If anyone know's the location of this .c or .h file, can you let me know or send me a DM?

Thanks,

~Eugene
[Vibrant Android Development] qreffie:
Exact same thing happened to me. You're going to have to Odin back to stock JFD and try again. Looks like you and I are one of the unlucky 1 out of 20 flashers. It's totally worth it though.

It's amazing. I turned my phone off around 2am (after unbricking it and reflashing), and when I woke up still had 97% left. It's draining about 1% per hour like it should now.

The stock JK2 kernel you can flash with R12 is on the first page listed as EB Productions stock kernel mod. I wouldn't recommend flashing it as I already tried it and battery life wasn't much better on that than the kernel R12 comes with. If you want good batter life, flash one of the A-series kernels A9 or higher, or flash R11.
[Vibrant Android Development] Sonnislav:
Running TW 4.2 Obsidian ULF with A12. All the tweaks turned on from CWM. Very snappy. Then played with Voltage but phone froze twice. Also it was perceived to be more laggy so left the Voltage alone afterwards (might also be that I screwed around with the scheduler option in Voltage but that may have conflicted with the tweaks that were done in CWM).

Battery is so-so. Running with dim screen and Superpower but also with Beautiful Live Widget and Live weather screen wallpaper. Figure if I run with just a blank black screen wallpaper (which I did try for awhile), I might as well switch back to my two tone Nokia...
[Vibrant Android Development] eugene373:
By Holding Power & Volume Buttons you can get back into recovery to Perform any Action you want.. You don't have to ODIN..
[Vibrant Android Development] smashmouth:
Currently running 4.2 w/ overkill jfs. Just loaded the new A12 OCUV. Setcpu is seeing the 1.2Ghz so far so good. I've rechecked the recovery menu and everything is in place. Boots nice with no issues, checked gps, calling, flash. games.. no issues to report.

Will run the phone in moderation today to see what the battery life is like before a recondition.

As stated everything is great... Great Job!!

and Thank you!

[Vibrant Android Development] krylon360:
Eugene, this is coming from one dev to another..

DO NOT! edit those files. you will cause a hard brick. It's been tried, and failed horribly.

The Logo you are looking for is actually in the SBL.bin You'll have to edit it in there.

We are attempting to do this as well, but are happy with are TW boot image.
[Vibrant Android Development] qzmp010:
What's the difference between the jfs and ext4 filesystems?

Are there any advantages to using one filesystem over the other on our phones?

I just want to have a basis for deciding which lagfix to use.
[Vibrant Android Development] phonepersonality:
I've reverted to the B_Stock_1120 kernel on my Obsidian V5.

It appears to be more stable and reliable than the B_1120_100 for now. This particular ROM caused me all kinds of grief today after initially appearing to be fine. Freezes, Lockups, disappearing home screen icons...etc.

Quite the adventure, actually :)
[Vibrant Android Development] firefly6240:
this might help a bit: http://mydeblog.hostcell.net/2009/04/24/big-file-system-battle/

as for using them on our phones, it depends who you ask. its mostly personal preference. :)

this subject is pretty heated in linux forums too, but most people seem to really like JFS alot.

EXT4 is the closest competitor.
[Vibrant Android Development] hurrpancakes:
Great read for Android power user noobies, if that makes sense.
[Vibrant Android Development] jcc332006:
When eugens states that on the latest kernel one can switch back to stock does he mean we can just flash back to stock in CW without having problems? Thanks.
[Vibrant Android Development] qzmp010:
Thanks for the info & link, but I'm kinda confused by that table that compares performance and reliability. Does the table say that JFS is more reliable than ext4 but provides less performance (because of the "<" arrows), or is it the other way around?

Back to the main topic:

[Might be a bug with the new B 1120 #20 kernel]

I've had an instance where after I brought my vibrant out of standby, the phone was lagging like crazy but not crashing. So I opened systempanel and saw that the cpu was stuck at 100mHz (and I wasn't using setcpu at the time). I managed to open setcpu and move the slider around and everything was back to normal.

I'm using the new B_1120_100 #20 kernel w/ Macnut R12. Just flashed it over the first released B kernel. I'll report back if it ever happens again.
[Vibrant Android Development] bobbbb:
What's the best kernel to flash if I'm running AOSP ish JK2 1.1 ROM? I really just want improved speed coupled with long battery life :)
[Vibrant Android Development] takato23:

[Vibrant Android Development] ttabbal:
Eugene: Could you share how you fixed the sleep issues please?
[Vibrant Android Development] BoomBoomPOW:
Very unstable when setcpu app is running. Freezes when the cpu gets stressed. That's with ondemand. I'll try conservative.
[Vibrant Android Development] cashyftw:
Just and update on battery life with the Bkernel

1d 0h 7s since unplugged, and I still have 21% If you haven't installed super power from the market yet, I invest you do so! :D
[Vibrant Android Development] lorendroll:
I get 75-80% charge left if doesn't touch my Vibrant for 24 hour of sleep on the stock (not B) kernel. B kernel eats 3-4% per hour in sleep.
[Vibrant Android Development] cm1ck:
SystemPanel monitoring still shows System Processes (especially suspend and sensorserver_ya) and system eating up a lot of resources while the phone is sitting in standby... Unacceptable levels, averaging around 4-5% and peaking sometimes around 10% for periods.
[Vibrant Android Development] krntehknik303:
Hahaha, dude I get 6% cpu activity on suspend when my phone is just chillin online. I'm going to test out the SuperSaver App or whatever its called by XDA and see if that helps.. if not I'm going to try and Odin back to stock, reflash, flash the kernel and do battery stat wipe. See what that does for the next couple days. Hopefully, there won't be new Roms just yet Lol.

Btw, I'm on Kernel 1120_100 Eugene's w. Obsidian v5 Beta. (So far this kernel has been the best, no glitches, etc.)
[Vibrant Android Development] cm1ck:
I'm on MacNut R12 with kernel 1120_100, did the Odin flash back to stock after removing all lag fixes, did a full recalibration and wiped battery stats per instructions. SystemPanel monitoring was done while WiFi, Bluetooth, GPS were disabled.

Battery life is just nowhere near stock, and despite what is being reported by a very small few, this new kernel does not seem to have improved battery life very much at all. Sorry if that pisses people off, but all empirical evidence suggests that battery life still sucks while the phone is idle and the screen is off. Of course, I like the build and give plenty of props to Eugene for what he is doing - it's difficult to make major strides without source from Samsung.
[Vibrant Android Development] krntehknik303:
I did the basics by disabling un necessary data users. Like how you stated. Also disabled background data sync. Seems like I still can't match up to others battery life. I even did battery swype as well and odin back to stock etc.
[Vibrant Android Development] ilaf0106:

[Vibrant Android Development] deez1234:

[Vibrant Android Development] jcc332006:
So is this an unreleased version of eugenes kernel? Dont see it mentionef in the op? Whats the advantage of A over B?
[Vibrant Android Development] cashyftw:
I'm using jfs overkill.

Sent from the speed demon
[Vibrant Android Development] bobbbb:
Logically, B > A, as it comes after it in the alphabet. But seriously, i'm not sure. i've heard great things about B stock kernel...
[Vibrant Android Development] firefly6240:
the "A" series of kernels are the predecessors of the B series.

the A series had some great kernels, but also included good chances of data corruption due to the Universal Lag Fix, making it nessisary to use Odin to clean it up before flashing a stock kernel (otherwise risking a soft brick)

these kernels were removed because of this.

The B series kernels thanks to Eugene, have eleminated the data corruption and are the better choice to use.

some people liked the fact that there was an A overkill kernel that allowed overclocking to 1.3 GHZ for people with processors that could handle it.

but there will be more B series kernels :) just be patient.

I would imagine Eugene is pretty busy working on Macnut R13 at the moment.
[Vibrant Android Development] bobbbb:
I'm just waiting on froyo to actually be released out into the wild here in the U.S. so the devs can actually get some solid source code and pump out some awesome(er) roms.
[Vibrant Android Development] palmdoc99:
I have never been able to run an OC or ULF kernel untill this one. And holy crap it is nice. My advice to anyone having probs is odin from stock2.1 or 2.2 flash your fav rom and embrase the excellence.

Pardon me I am a little drunk but none the less this kernel smokes
[Vibrant Android Development] jcc332006:
Ok I didnt know A came before B. Lol! I thought Z was first. I havent seen eugene posting about the A version of this kernel so that was the nature of my question ive tried the B version of this and phone continually froze. I was kind of wondering what advantsges this kernel has if any over B. Is this an unrealsed version of his kernel and if so what has been your results? Thanks!:rolleyes:
[Vibrant Android Development] jcc332006:
What kernel A or B?
[Vibrant Android Development] firefly6240:
The A version included the data corrupting version of the Universal Lag Fix so it was discontinued and replaced with the B series, my post on the las page explains it ;)

but there were quite a few A series kernels one of which could overclock to 1.3 Ghz, and another that could do 1.2, otherwise the B-series is the better kernel since the data corruption is fixed now.

also if your phone is freezing, try set cpu, and set the low end to something above 100 mhz.

some people have trouble with that freezing the phone, usualy when waking up from sleep..

my experiences with the whole A series of kernels was pretty good, however until the last A series kernel, my phone would die when sleeping.

the only way I found around that was to keep it clocked at the maximum speed the kernel allowed.

so the last A series and this new B kernel have been the best for me.
[Vibrant Android Development] jcc332006:
Ok. I didnt see Kernel A1120 only B1120. I understand the differences between A & B as I have the 1.3 version saved. I think what threw me off is the fact that I havent seen eugene stating that a A1120 version is available. Thanks for chiming. Preciate it.
[Vibrant Android Development] firefly6240:
oh yeah, the "A" version was only available for like a day, so it was pretty easy to miss, then it switched to B series with the same clock speed :)
[Vibrant Android Development] palmdoc99:
B its the latest one
[Vibrant Android Development] kevinngu:
my phone kept crashing with this kernel. its fast though. but it crashed on me twice. so i tried flashing back to the stock kernel (the file you provided) but i can't mount my phone to my pc! :'( i guess i'm gonna flash back the crashing kernel for now until i have time to fix it..
[Vibrant Android Development] firefly6240:
what do you mean by crashing?

was it a kernel panic?

or was it like freezing or not waking from sleep?

or like a soft brick kinda thing?

if its freezing or not waking from sleep, try starting fresh using Odin if possible and going back to JFD or whichever firmware and rom you like to use for that purpose, and then reflash your rom and then the kernel (if you did not do that in the first place)

or try using setcpu and setting the low end to something higher than 100 mhz.

(you could also just set it on performance for a while, this will drain your battery faster but if it works on performance then its probably a clock speed issue, in which case just play with the low end setting untill it works for you.
[Vibrant Android Development] kevinngu:
crashing as in i'm trying to access some menus/apps from my phone and it gets completely stuck.

so how do you set the cpu? is that an app?
[Vibrant Android Development] kevinngu:
crap ok so i dled setcpu, my phone just froze again after installing it.
[Vibrant Android Development] firefly6240:
what rom are you using?
[Vibrant Android Development] ellopr:
Doed anyone has problems with GPS with the latest B series kernel. I just when for a Run and never got a fix on a single satellite after 50 mins. I did disable network positioning (which does not work on PR anyways, at least on android). No sensor positioning either. Running Magnum R12. It was working with the A series - same Rom. A gps tracker app saw 6 satellites but couldn't fix in any single one. I am so tire the crappy GPS this phones has. Is almost december already and we don't have an official froyo update. My batteries are dying like crazy (using two daily and still can get throught the day completely, this is absurb.

Still I am so greatful for Eugene, without him I would had give up on the Vibrant long time ago.
[Vibrant Android Development] Robert8457:
My phone is freezing with setcpu too running macnut r12
[Vibrant Android Development] Sh8dyDan:
Ok, this whole issue with roms, kernels and battery life has drove me crazy for over a week now. I have finally found a solution which is suitable for me at least and I thought I might share it.

I'm a purest when it comes to ROMs. I like the ROM to be as close to the original as possible and Macnut is that. I do not see the need for lag fixes, overclocking or unvolting the OS or the kernel. I do like and appreciate the extra features that are added. I think TW spends to much time over themeing their ROMs. I like how Eugene focuses om the ROM nand not themeing.

What I use:

Macnut R12

Stock Vibrant 2.2 Kernel from TW website.

The Setup:

WiFi On

GPS On

GSM Only (Edge) I only switch to 3G when out of WiFi range and need data.

With this combo, I am getting about 42 hours battery life with light to medium use.

GPS locates 12 satellites and locks on to 9 of them.

With the stock kernel, I do not have the ability to OC, UV or apply lag fixes, I have to apply SD mounting fix to get both drives to mount and I still have the 2.2Gb limit of external SD. Like I said earlier, I perfer this and can live with SD limit.

The screen shots below are of my current setup

Battery is on first charge cycle, only going to get better

LbsTestMode for sats, a cold front came through very overcast, but I still get 7sats and 7 locks, that rocks

[Vibrant Android Development] gozilar84:
im using axura 2.0.5 too with setcpu on profiles set..so far i don't see any crash or freezed. Maybe few FCs on the market..

the only issue was the battery life seem drained faster than Axura 2.0.5 or Bionix_Obsidian without the battery condition. So, i am doing the battery condition now and will see it again for the battery life...

EDITED:

After the processed of reconditon for the battery, it still drain in a faster speed compared to the Original Axura 2.0.5 or Bionix_Obsidian.

I think i flashed back into the original Axura 2.0.5 kernel with voodoo lagfix

Just installed the latest B series on an Axura ROM (2.0.5) havent personally tested GPS just yet since on the island I dont use it much, but in FL it goes nuts and "ghosts" into side roads even when not moving. But Network positioning does work, I use it for my weather widgets and works fine.. Also I work 12hr shifts and often times get very bored at work and facebook, browse and check a few videos. Often times (90%) of the time my phone lasts about 13hrs, just slightly more than my shift. I try to stay away from watching nonstop movies though. Not sure if this is of any help but LMK
