Hello, I'm testing bhyve on an arm64 board, and it fails on a basic use case. Setup: - board: EspressoBin - FreeBSD 13.0 (https://github.com/FreeBSD-UPB/freebsd/tree/projects/bhyvearm64-refactor) Steps to reproduce: $ kldload vmm $ cd /boot/kernel $ bhyveload -k kernel guest $ bhyve guest The following error appears almost instantly: `arm64_handle_world_switch:534 Unknown exception type: 1514243680` After this, the board stops responding and requires a hard reset. Debugger doesn't kick in either. It's not completely frozen though: I can see new kernel messages regarding the attached usb drive. I believe this might be interesting to people working on bhyve. Ps. I can collect additional information if needed, feel free to contact me either here or privately. Respectfully, Kamil Koczurek
