Hello Azik,

please keep the buildroot mailing list on CC...

Many Thanks for the information. I did find some time to take a closer look at
the Brummbeere build system. It seems to invert/abuse the buildroot logic.
Instead of making Brummbeere a proper buildroot package it invents a
custom build logic around it resulting in a fancy mix of:

- Raspbian original SD card partitions (and rpi-firmaware files, e.g. bootcode.bin,
  fixup.dat, start.elf)
- a fixed (but old 3.18.x) buildroot compiled kernel
- a buildroot up to date root file system (git latest)
- undetermined precompiled (and checked into brummbeere git) brummbeere executable

Maybe this mix is the reason for the kernel panic shown in the other e-mail by you:
