VM with NIC Passthrough can't restart itself

[GeorgePatches]

I have a 13U4 server and a VM that I'm passing through a NIC to. It works pretty well, everything functions as expected while the VM is running. The issue I have is if the VM tries to restart itself. The guest OS will do all it's shut down procedures, I can watch all the threads associated with the bhyve process for the VM terminate and disappear from top, and then just crickets. The VM does not reboot no matter how long I seem to wait, and it still shows as running on the VM console. I have to restart or poweroff the VM manually for the VM to reboot. It's like it did all the stuff to reboot, but then just forgot to reset the VM. If I use the VM console to request a restart, it seems to work fine. Same if I shut down the VM, either from the VM console or within the guest OS, both work fine. It's just initiating a restart from the guest OS, and only with the PCI passthrough, virtual NICs do not have this issue. Anyone have an ideas before I file a bug report?
