Dev note:
Bug like music crash on CM13 still on progress to fix. maybe will take a longer time for this and i hope i can solved this one
If you take CM12 Based kernel, you faced camera bug and probably audio bug if you using this kernel. You can use CM12 based rom with uptodate source to solved this problem quickly.

Okay, I flashed this kernel on mokee latest stable version
I must say kernel has lots of tweaks and features.
In term of performance wise it's great and fluent animations.
Well we have so many governors and hotplugs.
Mokee with stock was lagging but with octopus kernel working without a single lag.
Multitasking also smooth.
One word for this kernel it's ...mind blowing
Thank you dev

@ocoot I've flashed it over CM13 nightly and it works very nice. It has many things that can be tweaked and it performs great. I simply love it.
The only issue I've found is that the headset controls are not working. This seems to be a common issue to all the kernels based on official source. Jerrica and Berserk-Jerrica also have this issue. Maybe someone can look into it? CM based kernels have headset controls working fine BTW.
Many thanks for this kernel!

I have the Xiaomi Piston 3 and with this kernel the volume controls do not work. With stock CM13 kernel they do. Also, the music cannot be played with any music player or file manager. This issue is also present on Jerrica. My model is 2014811 1GB, if that helps.
I'll provide logs as soon as possible

---

@ocoot Here is the logcat about the music playback and volume controls issue. I think i'll tag also @premaca because as I said this happens also on Jerrica for me. I hope i didn't bother you by tagging both of you on this response.
For more details:
ROM: CM 13.0-20160908-NIGHTLY-wt88047
Kernel: 3.10.49-octopus-g6a3da7c
SELinux: permissive
I didn't touch any kernel configurations and I don't use any audio mod. I've tried playing music with stock CM13 player, Shuttle+ and the file manager Solid Explorer. All of them try to play the song and it gives an error.
Many thanks for your contribution!

so far so good, this kernel should be available when cn14 released for our device

---

thermal control is not working properly,errors in the records hotplagov-1 core at the maximum frequency, the rest sleep

---

What about F2FS suport?

---

Nice to see more and more kernels.
Will try and report for sure, Greetz.

It's the kernel based on official sources, the kernels based on kumajaya's source have no issue with music playback on CM13. I have the same problem

Plss Increase the incall volume it is two low when compared to CM Stock kernel.

---

Sometimes when the device reboot, CPU stuck at lowest frequency and need to reboot again to fix.

---

when exiting sleep all the nuclei fixed at the maximum frequency.any hotplage.
This happens with any change frequency settings, or govornona hotplaga
P.S. after switching off locations all earned.very good core

you plan to update security patches?
