=== Troubleshooting ===

==== Preparations ====

* While compiling the kernel under Ubuntu you can get a beautiful error - "Your compiler is too buggy":

  $ make -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- dtbs
  CHK     include/config/kernel.release
  CHK     include/generated/uapi/linux/version.h
  CHK     include/generated/utsrelease.h
  make[1]: `include/generated/mach-types.h' is up to date.
  CHK     include/generated/timeconst.h
  CHK     include/generated/bounds.h
  CC      arch/arm/kernel/asm-offsets.s
  arch/arm/kernel/asm-offsets.c:54:2: error: #error Your compiler is too buggy; it is known to miscompile kernels
  #error Your compiler is too buggy; it is known to miscompile kernels
   ^
  arch/arm/kernel/asm-offsets.c:55:2: error: #error and result in filesystem corruption and oopses.
  #error and result in filesystem corruption and oopses.
   ^
  make[1]: *** [arch/arm/kernel/asm-offsets.s] Error 1
  make: *** [prepare0] Error 2

(It looks like GCC v4.8 is not welcome - it is too old, but this is just a guess)
