Just curious how you determined this? I was just thinking, with needing the delay, maybe that's the issue with the newer versions?

I tried manually enabling swap and got insta-crashes. I also seem to be getting random reboots with swap on 3 and 3.1, I'm not sure what is causing it
 
I have been busy with work but I also started to get random reboots I ended up switching back to the stock kernel but I have a feeling I'll be flashing back to Uno but I do see a performance gane with swap enable

I'm just running swap on stock kernel using what features it has... Running well enough.

You guys made me think it was something I was doing wrong with the Uno kernel regarding swap lol
 
Sorry about that I haven't had any free time (work and kid's)as soon as I get some free time I would like to tinker with swap maybe try to get it going

The following pastebin link is the /proc/last_kmsg log I got trying to use swap on volt uno 3.1 (voltunov3-1.img)

Well, good and bad news. Bad news is there's no crash in that log. Good news is that there may still be a clue. Log shoes the kernel was compiled with Linaro GCC 2015.03 - Cortex-A15. This is an issue because the 8926 doesn't use krait/A15, it uses a cortex-A7. The kernel will be compiled with instructions our cpu doesn't understand. Whoshotjr2006 needs to switch to A7.
 
He hasn't done anything with this in a long while... Might be up to someone else to do it. I'd give it a try if I had the slightest clue as to where to start.

If you are going to try a compile, could you add in "binfmt_misc" support? I wanted to mess around with the linux deploy app that apparently has a compiled qemu and some scripts that make use of binfmt to run x86 and x64 apps on arm. I know it will probably slow as molasses but something cool to try.

Looks like I can. Fingers crossed it doesn't break anything.
 
The last time i compiled this, it was generally accepted that the linaro cortex a15 gcc branch held all the optimizations already for the a7. Things may have changed since that time as i have not kept up on the project, but its what all our sister devices were using so i went with it.

I used a modified defconfig for building the kernel, the answer is probably in that.

so here's the thing, to really optimize CONFIG_CC_OPTIMIZE_FOR_SIZE needs to be unset, but when I do I'm stuck at the LG logo
 
spock1104 So the build you just linked us to is OK for testing I don't mind reboots or a boot loop just dont want to fry my phone and buy the way thank you for all the hard work you do. my ZTE Awe is still running like a chap

Yes, the one I posted is OK. Used Linaro 4.9.4 to build, with Os optimization.
