Yes, I think this is normal. When we talk about memory nodes we're
talking about NUMA nodes which is unrelated to device tree nodes.

I'm not really sure what's causing the crash. Have you verified it's
this patch that causes it? Is it related to there being a hole in your
memory, does it work if you only have one memory node?

Thanks,

Logan
