I'm not convinced this is going to help. The userspace support comes up
quite late and the kernel blocking has already happened before that
point when I last saw these issues. This was why I just enabled the
virtio rng passthrough everywhere...

Is libjitterentropy actually helping your use cases?

Cheers,

Richard
