Since I do not own the device, please be patient, for I'll be counting on you guys for feedback.
I look forward to doing the little I can to make your device sexier :highfive:

Wow can't wait for this. We all need a good JB Kernel. zRAM and so many frequency oversteps, this has really got me excited!! The race is wide open . Thanks for starting this project. Good Luck .

---

Hey why not make a combo?
All powersave frequencies with OC?
I would like to have a combo like that!
Also add 100MHz.. very efficient at battery saving
Look forward to it
keep up the good work

---

LED ?
Working LED on JB ?

---

Yeah, make it combo so I don't have to downloaded both.

I wish I could do that. But its not possible to accommodate more values in the frequencies table in the Overclocked Version.
And I did not add 100MHz because it causes phone to lag and be unresponsive on most Governors.

@mr.drooly was my tester. I'm hoping that there were no issues.

Looks very promising, huge list of Governors, WiFi 5Ghz band and first JB Kernel with OC @ 1.2 GHz.
Testing, Performance Edition with Interactivex+SIO (200 MHz - 1.2 GHz) Will let you know.

!
all fast, but multitasking in this kernel very bad

Desktop always redraws, I hope this is temporary.

It's a rom related "bug".

redraw is related to ROM, not kernel

Last time I saw oc to 1.2 ghz there was a problem with the tables(vengeance kernel). Does this work normally?

okay, i have 1 feedback. could you make this kernel all modes can do multitask?

Testing with skernel now, I don't think it has so much redraw problem.
I couldn't install skernel with cwm, ended by fastbooting. Please check. No any led lights when I tried to restart phone.

I can't decide what version to download
I care about my battery life but I like smooth experience too...
what the people here recomend?
I use Ultimate Rom V8 (JB)

---

Testing for the last 20 hrs, speed is snappy overall. Multitasking (of over two apps) as pointed out isn't that great. Interactivex+SIO @ 1.2 Ghz - 200 Mhz seems the ideal for battery life which I see is better among others given the performance.
I think keyboard redraws is associated to kernel partially. I had lesser withdraws with the kernel Ashwin's Ultimate Rom. It has something to do with destroying processes which is still buggy in the port as of now.
