I have the exp kernel and set at 1400 with SetCPU with ondemand gov. Profile to underclock to 800 while charging and screen off. Doesnt get hot at all set up like this. It didnt get hot before I had the profiles running either though.
[Samsung Epic 4G Touch] wase4711:
Using Setcpu, oc'd to 1400, here are my profiles..
[Samsung Epic 4G Touch] Dj21o:
My battery is going pretty good this far and no LOS. :)
[Samsung Epic 4G Touch] rockky:
LOS aside, phone didn't move as sharply with Lost kernel on Midnight 2.1...put Midnight v3 kernel back on and system flies again.

Anyone else see this?
[Samsung Epic 4G Touch] maddoggin:
man i love this kernel chris youve done awesome work man got mad respect for you for deving for this phone not having one but could you please put the stock boot screen back on i hate that android scrren and would like my phone to at least look stock even though its heavily modified lol!! thanks!
[Samsung Epic 4G Touch] xlGmanlx:
When you set the governor to performance I don't think it hardly scales down so your phone is basically sitting at 1400 the whole time, at least that's how I understand it
[Samsung Epic 4G Touch] stangdriverdoug:
This = correct. On performance the cpu will stay reved up to maximum clock speed.

Does the cwm make backups on the internal storage because I tried and it keeps telling me there is no external sd card
[Samsung Epic 4G Touch] stangdriverdoug:
Pretty sure the newer CWM builds are storing on the external sd now.

Do you have a ext sd card installed?

[Samsung Epic 4G Touch] interhawk1:
i have no sd card installed i want to make a backup on my internal but it won't let me.. is anyone having this problem?
[Samsung Epic 4G Touch] stangdriverdoug:
I'm not sure you can change it. You may want to get a cheap sd card... Its better to store the backups on a ext sd card anyway.

[Samsung Epic 4G Touch] interhawk1:
got it thanks
[Samsung Epic 4G Touch] Pheno.menon:
Amazing kernel. It's both sad and awesome that outside devs can code better than Samsung's own..

Stronger signal overall and reception in places I had zero before. Also, no LOS so far.

[Samsung Epic 4G Touch] WhiteWidows:
Anyone else Linpack scores really low? Like in th 20's on multi-threading
[Samsung Epic 4G Touch] lballer69:
only with starburst 1.6
[Samsung Epic 4G Touch] WhiteWidows:
Yea im on that rom...what up with that?
[Samsung Epic 4G Touch] lballer69:
Dont quote me on this but i believe its because he removed drm processes .I havent had any ill affects but maybe linpak uses something that is missing which is causing low scores

edit:

This test is more a reflection of the state of the Android Dalvik Virtual Machine than of the floating point performance of the underlying processor. Software written for an Android device is written using Java code that the Dalvik VM interprets at run time. http://www.greenecomputing.com/apps/linpack/

ofcourse this might prove me to be wrong

A DRM framework API, which is exposed to applications through the Android application framework and runs through the Dalvik VM for standard applications.

http://developer.android.com/reference/android/drm/package-summary.html

Did a little more research i think i was right lol
[Samsung Epic 4G Touch] WhiteWidows:
Thanks for the info... I haven't noticed any ill effects but all I know is stock is in the 90's
[Samsung Epic 4G Touch] lballer69:
i edited my post did a little more research i believe that is the issue lol google is great
[Samsung Epic 4G Touch] chris41g:
Could always try freezing drm on stock and see what happens..
[Samsung Epic 4G Touch] lballer69:
i have froze the processes on every rom i have used on this device and the og epic and have never had this issue ..........but i remember removing drm from the og epic and it having the issue and others
[Samsung Epic 4G Touch] lballer69:
I tried freezing and removing drm on stock with lost kernel still got between 75 and 90 on linpak so maybe its something else.
[Samsung Epic 4G Touch] wase4711:
quick question on battery life..

running the latest stable version, I noticed that last night, I lost almost 50% of my battery, with nothing on, just sitting idle on my desk; normally, I would lose about 8-10%, b4 I rooted and put midnight rom with this kernel on..

Is that normal with this kernel, or is there something I can do?

thanks!
[Samsung Epic 4G Touch] acrown:
Don't post this kind of stuff on the StarBurstROM thread or you'd be asking for trouble, that's exactly what I did, and PhantomHacker could not handle it and told us to

I was getting low scores, in the 20s as well and that's the response we got.

A bit sensitive I'd say.

Edit: this was on StarBurstROM 1.6, on 1.5 I'd get mid 80s to low 90s.
[Samsung Epic 4G Touch] clamknuckle:
Go to menu, settings, about phone, battery use, then click on the graph at the top and post a screen shot of the graph here.
[Samsung Epic 4G Touch] wase4711:
unfortunately, the phone is on the charger now, so the graph will be meaningless at this point..

I will do it tomorrow am, after the phone runs all day..

thanks!
[Samsung Epic 4G Touch] greatlakesghost:
I push the drm stuff back on starburst last night and it didn't change anything. So you are correct with it being something else. What it is is the million dollar question but imo its not this kernel. I have used Chris's kernels dating back to the original epic and they have been the benchmark for stability and I can't say my experience with this phone has been any different. With that said, keep up the great work chris!
[Samsung Epic 4G Touch] silversx80:
OK, so I ran the Exp kernel @ 1600/Conservative and lost 10% overnight. On the plus kernel, I'd lose 3-4%. I then flashed the stable kernel and battery life seemed a bit worse than the OC kernel. Looking at the battery stats graph, the phone spent more time waking up, and more time staying awake that ever before.

I flashed the Exp kernel this morning (forgot to wipe cache and dalvik, whoops) and unplugged at 7:30 am ET and 99% on battery. Still at 98% battery, but no overclock right now. Only 2-3 bars in my office, WiFi off, BT on, email sync every 30 min, auto Google-account sync. Not too shabby.
[Samsung Epic 4G Touch] Tyie101:
0 Los issues in 20 hours. Normally I would have at least 2 or 3 by now. Running Starburst 1.5/w lost kernel. Thanks a bunch.
[Samsung Epic 4G Touch] sm_x:
can some1 post a mirror until devphone goes back up?
[Samsung Epic 4G Touch] -viperboy-:
I just got this phone and I'm really liking it. Not that Quadrant means **** anyway, but running stock with this kernel, this thing pushed out over a 4700 in Quadrant. I find it amazing how much more efficiently this performs over the EVO 3D in the same tests but I just thought I would share.

Great work on the kernel, Chris!
[Samsung Epic 4G Touch] sm_x:
mirror please !
[Samsung Epic 4G Touch] maddoggin:
so chris if you not going to put the stock bootani back can you tell me how i can change the bootani on this kernel please thius is the only thing that is bugging me atm. thanks!!!

[Samsung Epic 4G Touch] blawkhawk1w:
I just got LoS today. I tried to send a text, but it kept failing to send. I had 5/6 bars of signal (or so it displayed). Next I tried to open the internet but had no connection. Then I toggled Airplane mode on and off. LoS...the circle with a line through it. A quick restart and the phone was back to having a functional connection.
[Samsung Epic 4G Touch] Devi0124:
Where are you located? I'm in DFW and was not able to send text for about 5-10 minutes, did a restart and all was good. Wonder if it was a network issue... For me this was about 30 Minutes ago... between 2:30 and 3:00 Central

[Samsung Epic 4G Touch] Dj21o:
Got it too. South east Michigan. I didn't reboot, all is well after 2 days. :)
[Samsung Epic 4G Touch] blawkhawk1w:
I'm in Kansas City MO. I found the phone was LoS around 2:30 this afternoon. After the reset, I had 3 texts and a voicemail from 12:13. I only noticed because the phone was getting warm in my pocket.
[Samsung Epic 4G Touch] nyeazyone:
Never had the LoS happen to me till today. I flashed the exp to see if my battery improved. Just flashed, didnt modify anything throu setcpu.

Had stock rooted before this.

Just pointing this out. Thanks for your hard work!
[Samsung Epic 4G Touch] maddoggin:
he may be updating this i dont think he would mind but you should have asked!! the only reason for links to be down is to update.

edit* reason devs dont like people to post mirrors is because they cant keep track of downloads. just sayin!
[Samsung Epic 4G Touch] chris41g:
Mine are back up... I would prefer people download directly from me..

sorry for the downtime, host was migrating, and i was on a contract call all day.. and the new host requires .htaccess files for indexing
[Samsung Epic 4G Touch] maddoggin:
still getting error 403 chris!
[Samsung Epic 4G Touch] SupahDave:
I've been on this kernel since Saturday and I finally got a few (3-4) LoS's today. This is the first time I've had any LoS in about 3 weeks since I was using Bubby's Stock EB30. Guess I'm going back to that kernel until someone can figure out what the heck is causing these damn LoS problems. I don't care what any dev says tho, LoS is definitely caused by the kernels because the Stock kernel gave me zero problems.
[Samsung Epic 4G Touch] rickyq12:
Just thought I would mention my LOS...hadn't had one till today around 3 oclock-ish. I live in Austin,TX. I flashed losTkernel back on friday morning and didn't have any issues. So it looks like it was a network issue around that time. Other than that, this is flawless.
[Samsung Epic 4G Touch] Lento10:
Viperboy, glad to see you here.

Would your uv script work with this kernel?
[Samsung Epic 4G Touch] chris41g:
I dont even have this phone, and I lost signal a lot today... it was network related IMO...

also, try the stock repacked if you are going to give up on custom kernels... at least then you can still have CWM5
[Samsung Epic 4G Touch] jhgti:
working great no LOS in two days!! i had one a day even on stock. Now here comes a little request for the beta.

https://market.android.com/details?id=org.projectvoodoo.controlappdonate&feature=search_result

Is there any way to make this app work with your kernal. I had it on the nexus and made my screen look even nicer, plus it has some sound add on.

Thank you again.
[Samsung Epic 4G Touch] rdcrds:
I had 2 today with the Kernel and it is NOT related to there network.I understand you do not have the phone but LOS is just not dropping signal it makes it so you have to reboot your phone and unless you are looking at your phone you could have LOS for hours and not get calls.
[Samsung Epic 4G Touch] poppygt:
Quite a few people in the forums reported outages today around the same time. The problem is that with our phone you don't know if its the network unless you have another device handy. I've had two seperate occasions where I thought I had the ghost Los (no circle with the bar through it) and my friends Photon had no data service either.
[Samsung Epic 4G Touch] chris41g:
thanks but i understand the nature of LoS... was responding to the 4-5 people in the thread who all got loss of signal at about the same times today...
[Samsung Epic 4G Touch] Shoulon:
hey chris41g does the CWM5 backup kernels in nandroids?
[Samsung Epic 4G Touch] mprziv:
Battery drains much faster with this kernel, even at stock speeds.

No LOS though. Any ideas on what is causing the fast battery draining?
[Samsung Epic 4G Touch] chris41g:
it does on other phones ive used it one.. so i would assume yes.. but ymmv..
[Samsung Epic 4G Touch] Shoulon:
yeah i found out it does. But I asked because our OG Epic didn't backup kernels in CWM3
[Samsung Epic 4G Touch] musclehead84:
Cwm 2.5.1.0 did nit backup kernels but cwm 3.1.0.1 did back up kernels as far as I can remember.

Sent From My Evo Killer!!!
[Samsung Epic 4G Touch] Shoulon:
hmm.. Maybe I have SyndicateROM 1.2 mixed up with my CMW then? I do remember it didn't come with a kernel in update.
[Samsung Epic 4G Touch] greatlakesghost:
Could be anything from battery needing to be calibrated to an app hanging up on ya. Most people are reporting better battery life, myself included, so most likely some other factor.
[Samsung Epic 4G Touch] stangdriverdoug:
New version on the exp kernel is up. 1.0.0.4. Head on over to the IRC to get it. Working good for me so far.

Samsung Galaxy S II
[Samsung Epic 4G Touch] xlGmanlx:
What's new?
[Samsung Epic 4G Touch] mprziv:
Thanks for the response, I'll try to pin down the cause.
[Samsung Epic 4G Touch] ElAguila:
I occasionally have the battery drain issue. I had it before using this kernel so I don't think it is related to the kernel. It is a hard issue to pin down. My battery will drop 40% in the blink of an eye and the android os show to be the biggest drain but only used 1 minute of cpu. I have been better off using this kernel than not using it.
[Samsung Epic 4G Touch] Entropy512:
Plenty of things can cause awful battery - an app wakelocking, an app driving lots of network traffic to the phone (Skype causes lots of network traffic, and the nature of how this is handled causes the usage to be reported as Android OS instead of Skype), etc.

Exchange calendar sync (esp. Hotmail) is also a fairly notorious drainer. Some Exchange servers are OK, some kill your battery.

Also, if you have the same battery fuel gauge chip the I9100 and I777 do, calibration does not apply. Maxim designs their fuel gauges to not require calibration cycles.
[Samsung Epic 4G Touch] evohog:
5148 performance at 1600, this kernel is top notch. Thanks Chris appreciate it.
[Samsung Epic 4G Touch] greatlakesghost:
What I was saying but not as eloquently as you minus the fuel gauge. :-)
[Samsung Epic 4G Touch] TOralliart:
I've been on this kernel for about 4 days now. I've had LOS about every other day. Much better than 3-4 times a day.

My battery life is also better with this kernel. I can go all day now.
[Samsung Epic 4G Touch] halmo20:
On this kernel for 4 days here also and 0,that's right, zero LOS! Prior to this kernel, I got one or two a day.... Extremely happy with this kernel.!
[Samsung Epic 4G Touch] skandranon314:
Been on this for a few days now. Prior to this kernel I was getting about 5 los a day. Since flashing this, ZERO! :-)
[Samsung Epic 4G Touch] tdavis42:
This has done the trick. I never got LOS stock for 2 weeks then rooted with Z's v.3 root and started seeing it when going from wifi to 3g. Flashed this the other day and poof no more LOS. It will stagger when I am turning on music beta and leaving the house though. Oh well suck a killer phone I can deal with a little lag now and again. Thanks to the devs for your hard work.
[Samsung Epic 4G Touch] poppygt:
I flashed this about an hour ago. Went into the Samsung task manager and cleared memory under the ram tab and had my first Los. It usually drops service for a second and then picks right back up but this time I had to pull the battery. The good news is that I tried to duplicate it and couldn't. Just putting this out there to see if anyone else can force a Los this way.

Edit: It seems it was a fluke, can't get it to do it again even after rebooting and trying multiple times. My buddy was on his Photon when it happened so it wasn't the network.
[Samsung Epic 4G Touch] xPSYB0RGx:
is oc possible/easy on this kernel?
[Samsung Epic 4G Touch] Njnear:
Has anyone else experienced a wake lag when using this kernel? When running this kernel it would take my phone about 2 seconds to wake up from the time I pressed the power button. Stock and Zedomax kernels would only take about 1 second. Experimental kernel seemed to make it worse.
[Samsung Epic 4G Touch] R1ptide:
Orrrrr it could be the reverse and the other kernels have issues with wake lock

---------- Post added at 01:06 AM ---------- Previous post was at 01:04 AM ----------

Seriously though I'm getting a 4.6% drop in battery per hour and thats the best I've ever seen. I use my phone quite a bit, keep wifi on most of the time, and spend a good chunk of the day in low signal areas.
[Samsung Epic 4G Touch] lickarock:
MHL does not appear to be functioning in this kernel.
[Samsung Epic 4G Touch] Sycobob:
I can't say for sure yet, but I've been experiencing a lot of force closes since flashing this kernel. The only one I could consistently reproduce was with Skype. Enabling video caused the app to crash. I flashed another kernel and the issue went away, but when I flashed Lost again, the issue didn't come back. Maybe a hiccup from the first flash or something. I'll try to keep an eye on things.

Otherwise, loving the kernel. Running it for a week and no LoS. All other kernels have resulted in LoSs within 6 hours for me.
[Samsung Epic 4G Touch] ioos:
How do we know when the kernel has been updated?
[Samsung Epic 4G Touch] venumx:
you go to the ACS website in the OP and there are links to the downloads, i just have the index of the standard and experimental builds bookmarked, that way you can see if new versions are there... i would post direct links but im guessing chris41g would prefer you go to the ACS page and click the links from his post.

* REQUEST *

how hard would it be to build in the ext2.ko file into this kernel to enable ext2 support for booting to ubuntu. i recently tried to load ubuntu and it fails on the modprobe ext2 step... im guessing thats because ext2.ko is not put in the kernel..
[Samsung Epic 4G Touch] ioos:
Check out my response in the Ubuntu thread. Chris did confirm that his kernel doesn't have ext2, but the OP in the Ubuntu thread claims to be using a stock kernel which also doesn't have ext2.

[Samsung Epic 4G Touch] Dj21o:
Hello, I just upgraded my kernel to the newest version, and it says that I do not have a kernel that supports voltage control... Is that just on the older versions, or do I need to do something else to UV?

EDIT: Nevermind, apparently I can't read. I flashed an experimental kernel instead. :p
[Samsung Epic 4G Touch] dja2k:
Hey can you please post Linpack scores, trying to figure out something that changed from LostKernel or from Starburst 1.5 to 1.6\1.7. Don't know if its ROM specific or LostKernel yet. Thanks!

[Samsung Epic 4G Touch] dtwconsulting:
I went ahead and flashed this kernel and all went smoothly but I don't seem to have ROOT, or perhaps it's BB, not sure how to check. When I try to run Titanium backup it states that it cannot acquire root privileges. Phone info shows that the LoStKernel is installed.

How can I check/fix this?

TIA.
[Samsung Epic 4G Touch] evohog:
Here's a couple.
[Samsung Epic 4G Touch] evohog:
It might be rom specific. I'm on the newest lost exp kernel and tried it on 1. 7 and the scores took a dump to about 4100 in quadrant.
[Samsung Epic 4G Touch] dtwconsulting:
Went ahead and re-installed this kernel but still I have the same issue.

I did install another kernel prior to this kernel, this filename for that was: et4g-rootish5.

The only thing different I see is that I have a yellow warning triangle when the phone first boots up.

Would really like to get Titanium working so that I can restore certain apps and then do a full backup before moving forward and installing some ROMs.

TIA.
[Samsung Epic 4G Touch] stangdriverdoug:
Sure can.

You cannot overclock with the standard kernel. Try the experimental build.

Also, from the dev:

"DO NOT USE TEGRAK WITH THE EXPERIMENTAL BUILD

I recommend Voltage Control or SetCpu."

Man, get sick for a few days and busy with work and I miss a ton. Thanks Chris ..flashing now with my freaky cleaned Odin counter..here goes #1...

Anyone notice that the update for exp 1.0.0.4 went from the 10/18 to 10/20...same version # though..

"LoStKernelExp-1.0.0.4.zip	20-Oct-2011 20:25	4.9M"
[Samsung Epic 4G Touch] ElAguila:
I was wondering if anybody else has seen an increase in the number of LOS's when going from the 1.0.0.2 exp version to the 1.0.0.4? With the .2 version I would get an LOS every 3-5 days. With the .4 version I have gotten 3 of them already just today.
[Samsung Epic 4G Touch] Dj21o:
I have not had one LOS since I have been using this kernel. Any of them. What ROM are you using, and are you wiping cache and dalvik cache before flashing?

[Samsung Epic 4G Touch] PerlAddict:
I've been getting multiple LOS every day ever since I first rooted my phone using Zedomax's non-OC'd Kernel, so when I read about this Kernel, I thought I'd give it a shot ... only to find out the ACS forum is down. Anyone got a mirror for the latest non-experimental version of this kernel?
[Samsung Epic 4G Touch] xlGmanlx:
Why not Just run stock kernel + stock rom + CWM and not worry about los?

[Samsung Epic 4G Touch] xlGmanlx:
Don't get the obsession with this option
[Samsung Epic 4G Touch] nabbed:
What do you mean? You don't like nand backup/restore?

Or do you have a spare sd card which doesn't lag the wake up time for me?
[Samsung Epic 4G Touch] skandranon314:
I think you are looking for this.

I just checked, that option is not there. As soon as you hit backup it auto starts. Unless it is under a different menu. Not sure, never seen this available before.
