IOT_THREAD_STACK_SIZE (256) must be enough ideally. What is surprising is that
you are having such a long call stack with 1644 frames, almost as if there is
some bug due to looping. Can you attach the entire backtrace of the thread that
crashed?

Hmm, I tried setting up a Fedora 31 ppc64le virtual machine using qemu on my
x86_64 Fedora laptop but I'm having trouble getting it to boot :(.
