Kernel Panic with Buildroot Linux

Question

I (try to) make a complete minimal Kodi Linux system with buildroot from scratch, everything compiles fine and i also got it to boot but after some lines of console output and graphics reset it gives me a kernel panic error:

at arch/x86/kernel/smp.c:128 native_smp_send_reschedule+0x33/0x40

I have no clue why...

My buildroot config file: https://pastebin.com/7PC4zLEa

It turns out that im just a bit ..., i forgot that there is a inbuilt hdd. I had sda2 in GRUB configured but i had to use sdb2. Hope this helps someone.
