[MENTION=3835696]deaver_92[/MENTION] stuff like clock speeds and if you were undervolting, that might help. I get a SOD usually when not plugged in to a AC outlet im not sure about USB though. also idk if any one has noticed that some governors dont go lower than 400mhz once you underclock to 50mhz or lower, ondemand and alicorn(forgot how its spelled) are usually the only ones that do go obey the clock speeds. this might be an issue only with 4.3kernel though

Flowed Away From My Samsung E4GT!
[Samsung Epic 4G Touch] kvevand63:
I experience the same with pegasusq not able to clock lower than 400mhz. Currently running CM10.1 0908 nightly, sio/ondemand, 1500/100, blasphemy v6 test release. No issues, just really smooth.
[Samsung Epic 4G Touch] deaver_92:
I'm on cm10.1 9/01 nightly, overclocked to 1400/200 ondemand/sio. No uv. I'm also running crossbreeder. I'll stick with stock speeds for a couple days and see if anything happens.

I've only gotten an sod when on battery. It usually seems to happen when I unlock the phone, look at something for a couple seconds, then lock the phone again. Go to look at the phone 10 minutes later and all I get is a black screen.
[Samsung Epic 4G Touch] Clariel:
You shouldn't have to do do anything other than flash the new kernel version. (If you want to reflash everything for some reason: Rom then kernel then other mods.)

Noob question of my own: Can I just flash this over the most recent build from the dirty unicorns thread, or did you make enough changes that I would need to do a clean install?
[Samsung Epic 4G Touch] Krowbarr:
Running Pacman Rom here with v5 50/1.4ghz smartass 2/sio. Read ahead set to 2048. No uv. No SOD's. Battery life: priceless:D:thumbup:

We were born in a time where if something was broken we would fix it and not just throw it away
[Samsung Epic 4G Touch] Zxo0oxz:
As for the SoD, I still have a couple of things to clean up for the release. The clock speed problem though, I remember reading up on another SGS II forum, that this chip technically isn't meant to be run below 800mhz max, so I'll see if there's anything I can do about that, however it may not make it in this next release.

This is bone-stock AOKP built straight from the git. I have no idea how much was changed in dirty unicorns, but you can always make a nandroid and give it a try.
[Samsung Epic 4G Touch] digitalmorphinex:
I just came from DU and was getting reboots.. So I switched to your version of AOKP.. (Nice BTW) and have had one reboot.. I'm a noob with log cats but I bet there is a tutorial to help someone like me post log cats.. Anyone wanna point me that way? You should consider taking over AOKP dude.. :)
[Samsung Epic 4G Touch] Zxo0oxz:
As much as I'd like to, I don't really like AOKP. I mean, I like all the options it offers, but it simply lacks the polish that I've been used to having CM on pretty much every android phone I've ever owned. To be honest, the reboot in my build may be due to the incredibly unstable branch of my kernel built into it. I'm about to make the release within a few minutes, so I'd suggest flashing that over it.

One more thing I'd like to add: I'm incredibly new with first hand android modding. I've been using Cyanogenmod since CM7 first dropped on my atrix about 2 years ago, but never really went further than that. I got this phone back in July, and decided that I wanted an up to date build of CM10.1 since we hadn't been getting nightlies yet. After I successfully built a couple of nightlies, we got nightlies officially, so I decided to try my hand at kernel development. So bear with me, I'm doing my best, but I'm new to all of this. This brings me back to my point: for debugging roms/apps, there's a few apps on the market that can continuously watch logcat and make a copy for you. Keep in mind you can also watch logcat through adb, or a terminal app. As for kernel debugging, I believe /proc/last_kmsg is the only reliable interface, which can easily be collected with adb.
[Samsung Epic 4G Touch] deaver_92:
Ok regardless of random occasional SoD's I am loving battery life. Almost 15 hours of battery with 1.5 hours screen time and I'm only at 43%. I've had bluetooth on the whole day with occasional pandora streaming to my car stereo and Wifi on most of the day. I'm running cb as well so that could help some but wow! Great standby time!

As for screen time, a while back on v3 or v4 (don't remember which) I ended the day with 4 hours screen time (battery was dead at that point)! Major props to you Zxo0oxz! Best I've ever had!
[Samsung Epic 4G Touch] Zxo0oxz:
I'm glad to hear that. I don't really optimize for battery life, I really work on implementing small features, throwing in occasional optimizations when it makes sense. The reason I don't optimize for battery life is, for me, it's pointless because I rarely get a better signal than one bar of 1xRTT. Luckily, I always have a charger available.
[Samsung Epic 4G Touch] glenesis:
So far, so good on #6, since I deleted the contents of /etc/init.d. With the LZ scripts in the, my phone was running hot under #6. With scripts deleted, it all seems normal and nice. I live on SlimBean 4.2.2 build 7.

Thanks for this wonderful kernel!
[Samsung Epic 4G Touch] glenesis:
Just had a freeze while I was composing in the gmail app. Interestingly, my signal bars and wifi bars stayed live, and I got to watch them bounce up and down while I waited to see if gmail would come back to life in the foreground. It did not come back to life.

Here is my last_kmsg:

I hope that it helps.
[Samsung Epic 4G Touch] Zxo0oxz:
v6 released for 4.2. I'll try to get a 4.3 release out soon. This release is rather small, mainly includes updated to 3.0.96, zram with google's snappy compression, and a few small tweaks by the folks at ARM and AOSP. I planned to have more, but it was too big of a pain in the ass to get it 'stable'.
[Samsung Epic 4G Touch] glenesis:
Thanks a lot. I seem to have been getting occasional freezes when I received new texts or emails. I just got a second freeze using your v6 test kernel. Here is the last_kmsg:

http://db.tt/kDICoXcK

I am going to install your v6 release kernel now :) Thank you very much!
[Samsung Epic 4G Touch] rangerelf:
Working beautifully on cm10.1 nightlies, 1200/200 ondemand/deadline.
[Samsung Epic 4G Touch] kvevand63:
V6 installed to CM10.1/9015 nightly, alicornq/sio, 1500/600. No issues encountered, running smooth. Thank you for zram, set to 18% and confirmed working via DiskInfo app. Great job!
[Samsung Epic 4G Touch] jwhyte:
Is zram activated by default?

Edit: activated with trickster mod. Is there a te command to do it?
[Samsung Epic 4G Touch] gamepro602:
is it a bug that you cant turn off the lights on the soft keys?
[Samsung Epic 4G Touch] gamepro602:
It happens on every ROM I install this on, currently on cm nightlys
[Samsung Epic 4G Touch] kvevand63:
Go to /settings/performance/memory management. You can set it there.
[Samsung Epic 4G Touch] jwhyte:
Latest cm nightly lost it. Every other one should be under advanced settings.
[Samsung Epic 4G Touch] gamepro602:
Yea, through even if I check the option, it doesn't work:(
[Samsung Epic 4G Touch] kvevand63:
I am on CM10.1 091513 nightly/Blasphemy v6. I used Galaxy2Settings.apk (advanced settings) from a previous SlimBean build, pushed it to /system/app, rebooted. My softkey lights are disabled as I write this, all features of advanced settings are working.
[Samsung Epic 4G Touch] gamepro602:
Thanks, I found the problem
[Samsung Epic 4G Touch] Zxo0oxz:
There's nothing included to activate it. No init scripts or commands or anything like that. If you're using Cyanogenmod, you can enable it under the 'Performance' tab. Other roms, I'm not sure, but I'm sure theres a metric ****ton of apps in the market to do it for you.
[Samsung Epic 4G Touch] hakcenter:
Time to revert lzo so twrp can stop hating your kernel

If you're really busy I could fork and pull...
[Samsung Epic 4G Touch] Soured Lie:
zram is a no go for me on DU and v6:(
[Samsung Epic 4G Touch] Soured Lie:
Yeah I've tried setting it with trickster mod, Zram control, and performance control. I check swap in te, nothing. Check status in zram checker, zeroooo.
[Samsung Epic 4G Touch] Clariel:
I'm running dirty unicorns too, and als had no luck with zram. I fiddled around and tried it with 'zram enable' and got some kind of message that it didn't exist. I figured I was doing something stupid and was getting random reboots so I've downgraded to v5.
[Samsung Epic 4G Touch] Soured Lie:
Samsies. I also got some weird error that caused zram checker to fc with a message with a very long string of numbers.

Does ZRam work in v5?
[Samsung Epic 4G Touch] Zxo0oxz:
It's just a defconfig change anyways. I'll see if I can push a new build out tonight.

I'll try to research third party apps that will successfully activate it. The easiest way to tell that it's working is to open a terminal and type one of these two commands: 'free' or 'cat /proc/swaps'
[Samsung Epic 4G Touch] Zxo0oxz:
It's only in v6.
[Samsung Epic 4G Touch] Soured Lie:
Yeah that was my first try. I may try to make an init script to activate it. That's what I had to do when i built my first ROM.
[Samsung Epic 4G Touch] digitalmorphinex:
I got that fc error and close too.. I made zram checker a sys app and it worked
[Samsung Epic 4G Touch] kvevand63:
Im running CM10.1 0915 nightly with v6 and OKJ. I set zram at 10%, and using DiskInfo app to monitor zram. As of this post, DiskInfo is showing zram swap as 78.9mb with 2.8mb used. In OKJs main init.d script near the bottom, there is a command to execute zram swap. I tried the zram status app and yes it does force close. In any case, I believe at least on my device, zram is working.

Edit: with the previously mentioned TE command to check zram, it confirms what DiskInfo is showing.
[Samsung Epic 4G Touch] Soured Lie:
Did it tell you Zram was doing it's job, or it just stopped the FC?

[Samsung Epic 4G Touch] kvevand63:
No problem. Google Operation Killjoy XDA. It is a tweak package, been using it for a while on both CM and TW. Works pretty good.
[Samsung Epic 4G Touch] Soured Lie:
Did the killjoy deal- for some reason the cpu control is not controlling the cpu... I set governer, i/o. min max freq etc, but when I check it in performance, it is at default.

Zram isn't working still. Tried the diskinfo app, it just reports my regular memory, and in TE "free" reports no swap.

I'm not sure what I'm doing wrong. I'm not new to any of this and I'm not a Luddite. Everything else works with the killjoy deal though (entro etc, mem boost). Not sure why zram or cpu controller isn't doing it's thing. I even went as far as to remove TWRP and reinstall both the kernel and and OKJ with CWM. I simply think it's something that is incompatible with DU.

edit- just saw that he added 18% zram in the latest test release? Is this what you are referring to? I'm going to DL the latest test version and try it out.

Don't mean to be a pest, I'm fine running the kernel as is with no scripts. It's superb, but I want to utilize the new feature, you know, just cause.

edit 2- still nothing meh. I give up.

edit 3- ok now zram is there with 96mb (diskinfo), but it shows as not mounted and it's not using it. Free shows nothimg either
[Samsung Epic 4G Touch] Zxo0oxz:
The dialogue with the 18% is a cyanogenmod feature, that appears if the kernel supports it. FYI, the latest release is more up to date than the last test release.
[Samsung Epic 4G Touch] hakcenter:
Ya already changed it in my local, works fine with gzip, my guess is kernel size is too large for twrp since it has a lot of shared libraries
[Samsung Epic 4G Touch] Zxo0oxz:
Eh, that "feature" was just ****s and giggles anyways. I'll revert it later. In the meantime, I've been running the stock kernel on an unmodified cm10.1, I still get an occasional SoD/freeze. I think I'm gonna start debugging there, to see if I can alleviate the root of our problems.
[Samsung Epic 4G Touch] Soured Lie:
OK I got everything working in DU now. I had to use a combination of OKJ and trickster to get this going. OKJ just executed the command, while trickster activated and mounted the swap.

Weeeeee!
[Samsung Epic 4G Touch] beezie42:
Just curious but is 1.6ghz our highest clock setting we can achieve?

I'm able to get to 1.6 stable 24/7.

So mabey there is more speed we can achieve?
[Samsung Epic 4G Touch] gamepro602:
If we go any higher we will either burn the chip or the phone will go crazy, though they put 1.6 there for a reason, it's just a safe frequency for the chip to be overclocked at.
[Samsung Epic 4G Touch] rangerelf:
I've never been able to oc to 1.6, so ymmv :-/
[Samsung Epic 4G Touch] beezie42:
Ok I figured as much. I just do alot of pc overclocking. I'm always looking for extra performance. I was hoping to hit 1.8 but I'll just have to build a kernel myself for that. Lol
[Samsung Epic 4G Touch] Soured Lie:
Was the super fast USB charging changed? Mine went back to normal. Not sure if this is because OKJ or V6
[Samsung Epic 4G Touch] comptonhubbard:
what's your settings to get stable 1.6ghz 24/7
[Samsung Epic 4G Touch] ps3hacker3:
I must warn you that it is very dangerous heat will get to it quickly at them frequency's I over clock on PC as well with a custom desktop
[Samsung Epic 4G Touch] beezie42:
Honestly my phone doesn't heat up much overclocked to 1.6. Plus I just love pushing things to the limit. PC and Android.

And worse comes to worse these phones are on craigslist for $100 all the time in my area.
[Samsung Epic 4G Touch] ps3hacker3:
Haha yea you have the once very lucky chip in yours to be able to handle 1.6 pretty consistently have you stress tested it as well and seen how it acts?
[Samsung Epic 4G Touch] thedarksavant:
OKJ

Pretty quite in lately, so I'll venture a survey question.

Is anyone using OKJ with this kernel and CM 10.1?

I ask because the last time I tried that combo, my phone became very unstable. I'm pretty sure it was just left over garbage.

I completely wiped everything I could and started over, slowly adding to it. I'm now running CM 10.1 and this kernel. Does OKJ make any huge difference in performance or battery?
[Samsung Epic 4G Touch] beezie42:
I am very lucky haha. I've seen people say they can't pass 1.3. Well I haven't run a benchmark tool on here in awhile now. I'll have to do that again.

I do lots of multi tasking while using bs player float window to watch videos, I also use halo and none of it skips a beat.

I will say there are very random reboots but no more then with the stock kernel.
[Samsung Epic 4G Touch] gamepro602:
Well I think that cm was a bit unstable from the start :))

As for performance with OKJ, with entropy and an odexed ROM (Running beanstalk) its noticeably more fluid, and gaming performance is noticeably improved.
[Samsung Epic 4G Touch] kvevand63:
I am currently running blasphemy v6 with CM10.1 092213 nightly and OKJ 0915 release. Yes, OKJ does make a positive difference in performance, battery wise on my device a slight improvement. Upon installation of ROM, I use EL29 direct boot, wipe data, wipe caches, then use JB Format All X2 to wipe once again, then flash ROM and GAPPS (I use SlimGapps because I dont use all the apps included in regular GAPPS). Reboot to make sure everything is working, then flash EL29 via Mobil Odin to flash kernel. I do this with any ROM, whether CM or TW and never had a problem with left over garbage from previous flashes. Currently, I have had no issues with this ROM/kernel combo regarding stability, including previous CM10.1 nightly releases. I also add several tweaks that actually work (over many months of trying various ones) to build.prop. As my device is unactivated, I also uninstall the phone, contacts, voice mail etc APKs, so I could not report on stability issues regarding voice calls, texting etc. Overall, I am very satisfied with my device at this time, it is fast and runs ultra smooth. In comparison between OKJ and Crossbreeder with this ROM/kernel setup, I will stick with OKJ for now. But I am sure that there will be a Crossbreeder update soon. Btw, for adblocking, I use a hosts file that I have held on to for a while. Push it to /etc each time with a new flash and update it with AdBlock. No problems with ads.
[Samsung Epic 4G Touch] hakcenter:
I noticed a few commits went through... No gzip revert yet?
[Samsung Epic 4G Touch] Zxo0oxz:
I've been on vacation. Those were just a few fixes that I was able to squeeze in when I wasn't doing anything else. I'll thrown in gzip when work gets slow tonight.

edit commit pushed.
[Samsung Epic 4G Touch] Temaeus:
Hey, in general should we flash the kernel in recovery before the rom boots or after. Will there be any difference? A few have told me that it best to let the rom settle first then flash the kernel in recovery.
[Samsung Epic 4G Touch] jwhyte:
Let the ROM settle then flash kernel.

Edit: I stand corrected. Thanks for the clarification.
[Samsung Epic 4G Touch] rangerelf:
I've been flashing it all together: ROM, gapps, kernel, tweaks, v4a, and 2.3 fonts, in that order. Haven't had issues yet.

Of course, I have to reboot after installing the v4a driver, and the xposed toolkit. But that's no problem.
[Samsung Epic 4G Touch] Zxo0oxz:
It won't make any difference since the installer clears the caches, so by booting the rom before installing the kernel, you're just wasting time.
[Samsung Epic 4G Touch] wm388:
Just wanted say using this with latest OKJ has caused random lockups and complete freezes. Gonna try the stable OKJ
[Samsung Epic 4G Touch] jwhyte:
What rom? Give that a shot or start fresh. Clean install blasphemy see how it runs then add okj.
[Samsung Epic 4G Touch] wm388:
Forgot to say, CM10 nightlies. Maybe it's because of my CPU setup? 25-1000mHz, bfq, alicornq. 25mHz shouldn't be a problem because I've been using that setup for ages without consequence.

Gonna try a couple of things. Might be a theme/Lux/DSBattery Saver/Greenify.

Thanks bro
[Samsung Epic 4G Touch] jwhyte:
I run same governor io 50/900 shouldn't be your issue. Do you UV? What's lux?
[Samsung Epic 4G Touch] rangerelf:
This kernel, without tweaks, runs beautifully. But when I try to use Comadose (which includes Crossbreeder) it gives me the sods. In cm10.1 nightlies also.
[Samsung Epic 4G Touch] jwhyte:
Interesting. I wonder if it's the nightlies? I'm running bean stalk, v6 and comadose with no issues.
[Samsung Epic 4G Touch] Zxo0oxz:
Don't set the min below 200mhz. Not only is it unstable, it actually uses more power on this particular chip.
[Samsung Epic 4G Touch] wm388:
Wow, didn't know that, thanks!

jwhyte, Lux is an app, basically like custom auto brightness. I know CM has it built-in but Lux can go sub-zero to like negative brightness.

Turns out my problem (oddly enough) was having Vibrate on touch enabled. I usually don't have it enabled but decided to try it and my phone sorta FO'd. Reverting back; didn't like using vibrate with softkeys anyway
[Samsung Epic 4G Touch] hakcenter:
Basis for more power consumption?
[Samsung Epic 4G Touch] Prestige_DOPE:
Just wondering

What are some good UV settings for this Kernel?
[Samsung Epic 4G Touch] wm388:
Also curious on this.

Smooth kernel overall. Love the USB charging. Alicornq is dope
[Samsung Epic 4G Touch] :
It varies by phone. Try UV'ing -25 at a time.
[Samsung Epic 4G Touch] Zxo0oxz:
I don't have it on hand, but I was reading about another SGSII, and there was a very detailed post about how 200mhz was the sweet spot for power consumption on this phone.

Edit: these aren't the exact numbers but the basis was somewhat like this

say 200mhz uses 10 watts, and 100mhz uses 9 watts, at 100mhz it will use 18 watts to do the same amount of work that 200mhz would do for 10 watts. Basically, 200mhz is the most efficient per watt on this particular phone, as confirmed by measuring power draw.
[Samsung Epic 4G Touch] hakcenter:
Maybe for work, okay but not idling.

I just hope this kernel wasn't the reason your usb port died. It kicks ass
[Samsung Epic 4G Touch] Prestige_DOPE:
Is that possible?
[Samsung Epic 4G Touch] Zxo0oxz:
Well, technically, it this kernel couldn't possibly be the problem for two reasons.

1. the charging modifications do not exceed the specs for this phone

2. I've been running the stock CM10.1 kernel for 2 weeks.
