I find it a bit disheartening that the linked paper only tested one embedded CPU (MIPS) ... the rest were x86-compatible CPUs, which, with their looong pipelines, deep cache hierarchies, turbo-mode et cetera, are very prone to indeterminism.

So this serves the "my (virtual) x86 server needs entropy for HTTPS" case pretty well ... but embedded?
