[Solved] Lockups with newer Kernels

I noticed frequent lockups where REISUB would still work and I could even still switch workspaces, though nothing would load (sometimes I had a terminal open, but it would never show a prompt). It all started, I think, with the kernels > 3.17.
The lts kernel worked without a problem.
The program that triggered this most of the time is Kodi.
I'm using the -ck kernel from AUR optimized for my CPU, but the regular Arch kernel has the same issue. Recently in one of the other threads about freezes, someone suggested recompiling with, PREEMPT_VOLUNTARY. I did that and the problem was gone.
Now yesterday there was an update to kernel 3.19.3.-2 and now it seems PREEMPT_VOLUNTARY doesn't even cut it. So I checked what the lts kernel uses and it has preemption disabled, so I compiled with that set and am currently checking the results.

My question here really is as to why all that is: has it got to do with my machine?
Here are my specs:
Pentium Core2Duo E6700 3.2 GHz
4 GB Ram
NVIDIA Geforce GT 520

Edit: Solved, since it's not an issue anymore with kernels >4.0
