All those optimizations by archi is great thing. just compiled cosmic cm with those optimizations. so far looks good to me.

as cosmicCM is already is a 4.8 compiled rom without much modifications to cm11. i think RR will also respond well with 4.8 . Only thing kernel side remain little buggy with 4.8.

Will experiment more and will let you know.
[Galaxy Grand Duos i9082 Android Development] xenon92:
Does it happen on v3.04?
[Galaxy Grand Duos i9082 Android Development] skpadhi79:
yes..on latest carbon rom with nebula kernel 3.04
[Galaxy Grand Duos i9082 Android Development] sty_erk94:
I'm forget, but I think it does not happen on v3.04..

Because I'm always turn off the phone when I want charging my phone..
[Galaxy Grand Duos i9082 Android Development] Parth2187:
Yes, I'm also facing this issue, using carbon ROM and nebula v3.04.

Too much battery discharging in conservative cfq 1200 and 312 . what should be done for rough use
[Galaxy Grand Duos i9082 Android Development] xenon92:
I'll look into automatic booting when charger is plugged-in in "switched off" state. But it isn't a big deal.

I made the kernel to work when the phone is in SWITCHED ON state! It is working even when the phone is SWITCHED OFF!

Hehe.

Ironical.
[Galaxy Grand Duos i9082 Android Development] RIPPER:
This prb i had widout nebula also..u think its kernel issue.?

I faced this prb in early devlpmnt f of RR rom.i thght its a rom issue so i alwys charge fone switchd on:rolleyes:
[Galaxy Grand Duos i9082 Android Development] xenon92:
I have no idea what might be causing it. I'll try with stock kernel too. Maybe someone with pawitp's CM11 build with stock things might test and see this. I'll download his build and test it too after a few days.

I'll have to do some research on this.

Hmmm...

Hi xenon,

My phone several times getting blank screen and not responding, especially during browsing, and sometimes when open another app, after that screen going black and it goes to screen locked state with recents app panel.

Does anyone know the cause?

First I think because of my kernel setting is not suitable :confused:

Is this possible? Or Is it a issue on the rom?

I'm using latest RR rom v.5.1.1 with nebula kernel v3.10
[Galaxy Grand Duos i9082 Android Development] rs tony:
Hello, i don't own duos but i got s2 plus. I use nebula kernel and rr rom too, i got sometimes same problem.

I use at the moment v3.10 nebula kernel and 5.1.1 ressurection remix rom
[Galaxy Grand Duos i9082 Android Development] xenon92:
May very well be RR issue, and not the kernel issue per se. You'll probably face those issues on stock kernel too.

RR 5.1.1 have a few stability issues. Those were forwarded from CM source base. In 5.1.2 we merged few commits that fixed NPEs here and there and fixed a few SystemUI crashes as well. I didn't compile RR 5.1.2.

Will I? I don't know.

I am using Carbon about a week now and kernel seems to be working fine.

Hi, thanks for your support of the i9082!

I have 2 questions, if you have the time to answer.

1. Will this work on pawitp's aosp 5.1.1 ROM?

2. I need a kernel that allows call recording directly from the line. All call recorders that I've tried require this feature. Does you kernel support this? If not, will it be possible to add it in a future release? This used to work on the original OS that came with the phone (4.2.2), but stopped when I replaced it with lollipop.

Thanks and cheers.

[Galaxy Grand Duos i9082 Android Development] goku15:
Thanks xenon92 for the kernel. I have flashed the kernel and so far there is no bug. However the phone randomly reboots sometimes and sometimes there is fc in apps. Battery is awesome because of the O3 compiler as you used in slimbean
[Galaxy Grand Duos i9082 Android Development] xenon92:
FCs in apps are mostly likely caused by a faulty app state or a faulty ROM state, not by kernel. Look at the logcat to find the cause of your FC.

I haven't faced any random reboots yet. The kernel is quite stable. Provide as well as look into last_kmsg to see the reason for your random reboots.
