Now, I'm not getting good vibes from this test. It spawns QEMU and
then gets stuck on every single execution.
VM launch command: 'aarch64-softmmu/qemu-system-aarch64 -chardev
socket,id=mon,path=/var/tmp/tmpgpee0g1h/qemu-23397-monitor.sock -mon

Given that I've tested this before, and I see some changes to raspi3
since then, I'll try to bisect the possible culprit. If you have any
clues, they would be much appreciated.
