--- Comment #5 from Michael Ellerman ([email-masked]) ---
It's likely there's some 32-bit boot code that is being instrumented in a way
that causes it to crash.

We probably need to add some more uses of DISABLE_LATENT_ENTROPY_PLUGIN in
arch/powerpc/kernel/Makefile.

To start with you could try adding:

  CFLAGS_setup_32.o += $(DISABLE_LATENT_ENTROPY_PLUGIN)
