Keep in mind i have almost nothing installed. No Facebook no tumblr etc. The only thing I have that should do checks for stuff is whatsapp. Even went with minimal gapps. I used Wheatley, disabled mp decision, enabled intelliplug. Other than that not much. I disabled kernel samepage merging and use noop for I/O.
Go back to using mpdecision (disable intelliplug), that's the only thing causing green screens for me iirc.

You mean the thing i have posted in another kernel thread? I actually have 2 devices mine and my friends. They each have different kernels so i can test them. (he doesn't use the phone for calls he got a tiny **** phone and uses the lg for wifi idk why) 777 has been green screening so far no issues in this one but we will see.

On a side note i have now noticed that BFQ does not appear to be an option? i am going to keep using noop myself since it uses less cpu and i honestly do not do much I/O wise. Just wondering if anyone else noticed this.

tried the test verison 3gb KEXEC on multirom, got green screen app watchdog bark. No worries though, that WAS my experimental rom not my daily driver. Anywho the point is, why? isnt KEXEC supposed to be FOR multirom?

    Update to V2.1!

    ADDED:

    OC to 2,7Ghz and CPU Limiter by @Tectas
    (just for trying, it consumes more battery than it improves performance + maybe you have to reboot to set OC CPU clock if it doesn't stick)
