[Bug] Booting the VM kernel gives "Internal error: undefined instruction: 0 [#1] SMP" on Volterra #4508

Additional info: This is what CPU features Host and VM present to the kernel:
Does the VM just want to do something odd, like using SSBD even if it's not there? |

Describe the bug
Hi,
I was checking out if I could run firecracker-vm on the Volterra box (Windows Dev Kit 2023). It is booted into EL2, has /dev/kvm, and also an lxc VM running to check if VMs are generally available and working.
When booting it halts with the undefined instruction, not quite sure if it's a kernel config that needs to be changed.
Attached is the complete log, it boots the VM. And balks on the code.
start.txt
To get the vmlinux kernel I have set
export arch=aarch64
, maybe it must be more specific?To Reproduce
I used https://github.com/alexellis/firecracker-init-lab in addition to the firecracker how-to, came along nicely until the VM crashes.
Expected behaviour
It just works ™️
Environment
Additional context
I would assume that the kernel config for the guest kernel expects an ARMv8 feature that is not there in this chip?
