Unfortunately qemu 2.11.1(Debian 1:2.11+dfsg-1ubuntu7.32)
doesn't replicate this crash using the command line from
https://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/qemu-system-aarch64

It makes it all the way into the Linux kernel and user space
without crashing.  Hopefully someone with better access to ARM
hardware can help debug!
