It's not any one commit really, just creeping demand for more pages before the VM can get started. I would suggest making boot pages scale with MAXCPU. Or just raising it as the panic suggests. We could rewrite the way that the vm gets these early pages but it's a lot of work and typically people just bump it and forget about it.
