I'd be interested in a repo case too as I haven't seen the NVMe
emulation in bhyve do this before. Were there any error messages from
bhyve?

The guest log messages seem to suggest that the backing storage for
the emulated device is timing out. If your comment

means the host is seeing NVMe errors on the drives backing the
zpool/zvol used by the emulated device, this might explain it.
Although, it is curious the emulated controller had trouble resetting
(i.e., the error message "controller ready did not become 1 within
30500 ms").
