Of course, I'll see what can I do when I get everything (OC, UV, ...) working here waiting for a tester...

it is indeed slow. even when completely debloated plus stripped of "essential" system components that I personally do not use. I will try this right away. will report back within an hour in this post.


@Ziyan
it boots, runs, everything seems standard. not seeing any performance increases though. same ol' 10 to 15 fps is there anything more you wish for me to test with it? I replaced this tab a while ago with galaxy note pro 12.2 so I can't really use it enough to check for random reboots
Error 4.0.4 Android Not Found!

Please check your internet connection and don't spam the forums trying to figure this one out.

Thanks, that's good, it means I can continue improving it. I need to check the kernel periodically after a big bunch of commits, because if something gets broken, it can be hard to find what causes it if from a thousand things I'll push a new version and changelog later today or tomorrow.

I wanted to let you know that I am on the Pac Man Rom but can't get this to boot. Freezes up. Will have to try cm11 .

Ok, so I went back to cm11 but after flashing kernel it booted all the way but got a "google system error" message and it froze. I rebooted but would freeze on cm logo.
What am I doing wrong?

Did you do a factory reset after switching to CM11? If not, please make a backup (so you can get back your things if it won't work), do and then flash CM11 again with this kernel only. If it doesn't work, I'll make a special build for you test
