I also get reboots. Usually happens under heavy data usuage + tethering
[Galaxy Note II Original Android Development] easycure1974:
No way that it is just an user error. I am running stock rooted rom and had serveral random reboots with 29. Flashed 29.1 and it got better with just some reboots. With stock kernel no reboots.

But I prefer this kernel even though it reboots sometimes. Often at night when the phone is on the table besides the bed. It is no big issue for me but it exists so dont just blame the user as several others also have it
[Galaxy Note II Original Android Development] Frank2:
I also have reboots since Kernel 29. No new Apps, no new settings, nothing!
[Galaxy Note II Original Android Development] owl74:
Those having reboots, are you on international version of note 2 or carrier branded?
[Galaxy Note II Original Android Development] harun79:
I am using omega 9.1 and peraeua 29.1..battery drain so fastt..can u help me?

[Galaxy Note II Original Android Development] brightboy:
What brand of SD Card you use? I have the reboot problem too while I am using scandisk 23gb class 10 card.

After I change to another card (same spec. but diff. brand), the reboot problem has gone!:silly:

You could check that form google! Try another card!:victory:
[Galaxy Note II Original Android Development] astoncheah:
Those who are having reboot issue, i suggest to do the below step to help Andrei to investigate the issues more effectively rather than saying "my phone having reboot"

34. "I want to help dev debug an issue providing a kmsg. How to?"

A. After the problem (random reboot/freeze/lockup), do not pull out battery to recover. Just long press power button so that device can reboot. Then connect device to PC, (provided you have setup adb), type

adb pull /proc/last_kmsg

Save the file as .txt and post in the thread along with description of the problem and possible way to reproduce it.

If you can't use adb from pc, just copy last_kmsg file from /proc directory to internal sd, copy it to your PC and post in the thread.

i copied this from S3 Siyah kernel FAQS, i think it applies in Andrei kernel as well.
[Galaxy Note II Original Android Development] xiskillo:
I would like to know since a long time ago which is exactly problem that Andrei try to fix in your kernel... always with the same microsd Sandisk 64gb ultra class 10.

I dont know if its a individual problem with my card but for example I cant use well the Directory Bind app because however start works well.. the next indeterminate hours the bind not works but the app not show nothing bad...but not works.

Other problem too is with the Mod for exchange internal with the external memory.. first works well but in the next hours not.

I think that this problem can be caused by the typical problem message "micro sd extracted..." or "preparing micro sd" which can be the cause for this wrong function from directory bind and the other mod..

Someone have any idea or experience?

Finally sorry for my poor english, regards

Try changing modem/radio and also use betterbatterystat app to see wats causing the drain.
[Galaxy Note II Original Android Development] betoNL:
Just quoting a very good suggestion.....

Anyway I must be a lucky one :laugh:

Not one single reboot, phone is super-smooth and battery performance is amazing....

Of course I am careful with what I do with STweaks...

And the audio tweaks implementation....it's to die for....

although it's for Galaxy S2 you can do all the parts about BBS, Wakelocks

and if nothing helps do a full factory reset (don't restore from Nand or PC) and re-install everything.

hi .

im on omega .

i downloaded the perseus kernel.

i just need to instal by perseus CWM the perseus kernel?

Do i have to do something else ?

When i flash the perseus kernel will i lose omega rom ,or everything would be ok ?

thank you :)
[Galaxy Note II Original Android Development] Smartino666:
The kernel is separate from the rom so you will be fine
[Galaxy Note II Original Android Development] brightboy:
Totally agree with you. I Have just changed the another brand SD Card. The reboot & battery life issues have gone!:victory:
[Galaxy Note II Original Android Development] djsmeegy:
Hello. Wanna to say merry Xmas and happy new year;)

Also big thank to Andrei for great kernel. I've tested neak but much more draining battery than perseus.

Now I'm running on 29.1 with omega 9 and no random restarts - just with torrent managers. Great work. Great stability and smoothness.

Just two points. Do you think you can add led fading and current charge control?

Thanx and all of you have a nice time.
[Galaxy Note II Original Android Development] yehoshua:
I just flashed this it is quite excelent thank you.

I was curious while you are in there flipping our kernel bits if you wouldnt mind checking if the changes here

http://xdaforums.com/showthread.php?t=1835720

to enable charging while an OTG cable is connected could be incorporated into your kernel. There doesnt appear to be that much required to make the changes work but I am not confident enough to try it myself :D.

If you are interested the link to their code on github is on the 10th page post ... 94.

Thanks!
[Galaxy Note II Original Android Development] duowing:
I had my first reboot since flashing 29.1 today. I haven't noticed any reboots with this kernel since flashing it, and I pretty much flashed it as soon as it was released. I've done different things, watching youtube, browsing, playing games for long amounts of times while having people sending text messages etc. Anyway I wasn't really doing anything with my phone, set it down and while playing some Xbox I heard the boot animation sound and looked over. Sure enough my phone had restarted. It was weird. The only thing I can think of that I did different today was that I actually opened STweaks and played with it. I don't believe I've even opened STweaks since flashing the Poland 4.1.2 Firmware and 29.1

I'm on 3rd day and no reboot. I have to say once I flashed 29.1 I noticed Stweaks got installed but I froze it. I never changed any settings there.

[Galaxy Note II Original Android Development] quertiy:
Why is the notification led using neak kernel 2-3 times brighter? Literally. Or more. I installed it just for testing and when I saw the led being so bright I pulled the battery (so it wouldn't break - I touched it and it seemed very hot). And yes, I laughed too after realizing what I did.

I can now (again, literally) use the white led as a mini flash to find things in the room or on my desk, at night.
[Galaxy Note II Original Android Development] megh1982:
If the reboot is because of memory card... why only on Perseus, why not on stock kernel???

---------- Post added at 10:45 AM ---------- Previous post was at 10:22 AM ----------

STweaks settings change is causing reboots...

But if we froze it, we can not use amazing tweaks like Increasing db levels of headphone and speaker..

First of all, if you you don't mess around with it, and will use only the audio tweaks, you don't need to freeze it at all, in order to avoid stability issues......afaik

Today I had the very first REBOOT for no reason. I just used googlemaps to navigate for around 15 minutes, then I received a viber message, replied to it, put the phone in my pocket as I always did. Took phone out after 30 minutes and pressed the power button to wake th ephone up... then the phone rebooted. My battery was around 38% at the time.

I am on ARHD 6.0, never played with STweaks, and I have frozen it since I flashed 29.1 kernel. Installed apps are just Tunein Radio, Viber, Skype, MX Player Pro, Xposed framework, Speed Test, Dead Pixel detect and Fix, BBC iPlayer/BBC Media Player.

Only Viber was running in the background at the time of reboot.

This is not directly on topic but, you can export last_kmsg directly on the phone with Lumberjack so no need of PC for catching the log. I've had a couple of reboots now and then but was not near PC while had those. I just found this program and thought that it'd be good to share it.

Sadly I have to say that in the last couple of days I have been having quite a lot of reboots, without changing params of stweaks.

The error is triggered at this point :

I still have to narrow down what could be causing this behavior, as for now it is totally random.

Happy New Year to Everyone!

here is how i attached my "lastkmsg" file by using my n2:

1.copy the "last_kmsg" file from /proc and save to SDCARD or whatever location you know.

2.change the name to "last_kmsg.txt" (just add .txt extension at the back), if the file is bigger than XDA allowed, you may need to use some android zip app to compress it.

3.use "Stock Browser"(not Tapatalk XDA) to open XDA and go to this forum.

4.attach the renamed file like how you do with PC.

5.done!

hope it helps for those who wanna send the file to Andrei and without PC around!

[Galaxy Note II Original Android Development] EdgaBimbam:
hmmm using perseus kernel from beginning, always latest version, have changed some settings at stweaks but never got any reboot or artifact. Always using stock odexed firmwares, mostly polish 4.1.2. So maybe who gets reboots is because of custom rom or bad settings combination with this kernel? ^^

[Galaxy Note II Original Android Development] easycure1974:
It has been written in so many answers that even users running stock rom gets reboots so its not some custom rom that makes it reboot. I am also running stock rom and got some reboots but not very often so it is no big problem for me. But the issue exist for several users and it stops rebooting as soon as stock kernel is restored

[Galaxy Note II Original Android Development] AndreiLux:
Sorry but it's a bunch of nonsense. I don't want anybody using older versions and I don't want to see mirrors here.

I know some people are having problems, but almost nobody reported a single kmsg log if these reboots and I'm trying to pinpoint something without having the device and without anybody able to properly reproduce it.

I've found some inconsistencies but those were in since I released the kernel. The problem may actually come from v27 CMA related changes, so if you think it's stable then it's placebo.
[Galaxy Note II Original Android Development] nabilsweet007:

[Galaxy Note II Original Android Development] AndreiLux:
Witchcraft and borderline religious-like beliefs are not welcome here. You also don't "urgently" need it. Food, water, and oxygen is what one urgently needs, or an ambulance if you need healthcare. Not a kernel version.

There is no difference in battery consumption between 27 and 29 except for the raised maximum brightness in v29 which may consume more, if so, adapt your brightness levels.
[Galaxy Note II Original Android Development] betoNL:
Talking bout Witchcraft ...

The battery performance is so damn good with every rom and kernel I tried , that it feels like it ... Witchcraft :laugh:

Anyone using stock music player and has this issues? Sometimes stock music player equalizer resets and to enqble it again need to open equalizer at music app settings. :(
[Galaxy Note II Original Android Development] yahyoh:
yep i can reproduce it

go play some music then go to camera take pic the music will stop for about half sec then it will back without EQ its probably bug with music player it self ( maybe the sound driver IDK ) and i remember it happened with stock kernel too :rolleyes:

By the way I'd wish if more Note 2 people entered their voltages here because it would really help with my analysis. It also doesn't matter if you're on this kernel or another.
[Galaxy Note II Original Android Development] CekMTL:
So... After having some proper time to actually sit down and debug the reboot issues, it turned out in my case to be a completely fubared /system partition... Man when I launched e2fsck it was like watching the matrix... So I dumped it and recovered the last backup.

Stable for more than 24 hours with latest available kernel and doing my usual daily business.

So check if your system partition needs repair.

Twrp / adb / e2fsck...

How close to the extreme do you need it? I haven't had the time to fully UV my device, but most of the frequencies are probably within 25-50mv from being unstable (and I'll be surprised if many were 50mv off)

Thanks for the clarification :)
[Galaxy Note II Original Android Development] AndreiLux:
25mv would be good.

It's kinda weird that nobody with an ASV chip beyond group 3 has been posted. You all have crappy chips :) It's also ****ty that I can't differentiate groups by voltages for groups 1-3... I'll have to make an interface so people can directly read out the chip assignments.

Hi AndreiLux

pongster - the redpill kernel autor sad that he is found SOD bug (but he hast time to realise a new version right now). yours kernels are very close - may be, the same bug for both kernels?

also the neak kernel has bass boost option inda voodoo controls (like in dsp manager bass) - cant you add bass too?
[Galaxy Note II Original Android Development] AndreiLux:
As far as I know from checking his repository he didn't find the bug but simply rebased his kernel. Anyway I will be taking time with the next version as it will be big and hope to find the inconsistency myself.

I don't know what AndiP did in regards of a separate bass option but you can just increase it in the equalizer.

EQ and bass its different things. If you tryed dsp manager you must to know it )

its impossible take that bass with EQ )

i can use DSP manager, but its not works with some players that uses Direct Sound Control, but your kernel sound tweaks works fine EVEN with DSC. and if you add that bass i will delete DSPmanager and other sound tweaks )

for the redpill kernel: latest available version 1.00 has a SOD bug. But pongster sad that a new test version hasnt, but he isnt upload it

people sad that latest stable realise was 0.10.

also that tweak: Added dynamic Fsync control (Faux123) was added in 1.00 version.

i cant test 27 version because cant download it but may be bug in that tweak?

many people in redpill thread says that they has feezes or SOD when they tries to unlock device, or when they tries to download files via torrent or other soft while screen is off
