Ok, I was able to hit a similarly looking panic exactly when trying to run "bhyvectl --vm=altroot-bhyve --get-all" while the VM was busy with its own "pkg delete -af". When the VM is mostly idle, bhyvectl --get-all goes smoothly. Now I'm thinking I might inadvertently run bhyvectl over my heavily running VM once when I was not at the desktop and wanted to see how things were going remotely from my office...
