Custom kernels on Redmi 3

Has anyone managed to boot any custom kernel on their device? As far as I'm concerned every single ROM, available for Redmi 3 (whether it is CM12/13, Resurrection Remix or else) run stock kernels, built by Xiaomi. I tried to compile CM 12 kernel, CM 13 kernel, Open Source Xiaomi kernel, I used gcc 5, gcc 4, UberTC, Google toolchain, I tried modular kernel, monolithic one with no success. It just doesn't boot, though it has the same version and build settings as a stock one.

So am I doing something wrong or Redmi 3 is indeed vendor-locked to boot only Xiaomi kernels?
