Most of the crashes ~70% happens when Windows restarts and one has the
bhyve-uefi-picture and the spinning dot on screen, but sometimes in the middle
of a update when logged in to Windows.

Additionally the crash happens more often with enabled passthru, but also
without.

The two devices in vm-bhyve_Windows.conf are a GPU (AMD RX580) and a USB-Hub.

Changed to another tty to see some messages, restarted the Windows Guest, zero
messages but reliable freeze and hard reset.

This is not happening with Linux/BSD/OpenVMS/9Front/omniOS really just with
Windows10/11 and the corresponding server variants.

To me it "smells" a bit, but not really like that Forum entry:
