That is great; I'll add that to my own tests to get some output.

Interesting. I was able to confirm that the lz4 patch is not the root
cause. I was not able to reproduce the problem in v4.10, but after
adding more and more configuration options I get it to fail starting
with commit ac1820fb286b552 ("Merge tag 'for-next-dma_ops' of
git://git.kernel.org/pub/ scm/linux/kernel/git/dledford/rdma").
No idea if that is the root cause either. Kernel configuration for that
case is attached.

Of course ac1820fb286b552 doesn't crash anymore with that after applying
your patch below, and v4.11-rc1 crashes without any output :-(.

I think I'll add some logging into qemu to see where it puts the dtb.
