Bhyve OpenBSD 7.6 not working any more

Hi All,
     I plan to use OpenBSD 7.6 guest with bhyve on a FreeBSD 14.1 host. With
the release candidate of OPenBSD 7.6 I was able to pass two network cards
with PCI passthru to the OpenBSD virtual machine.

With the production version of OpenBSD 7.6 the PCI passthru does not work any more. Even
worse if I try to install OpenBSD without network card I get the message
produced after this mail.

The problems arise (with the PCI passthru and without network card) immediately
after the message "entry point at...".

The command used to start bhyve is:
/usr/sbin/bhyve -HPSD -u -s 0:0,amd_hostbridge -s 31,lpc -l com1,stdio  -s 4,nvme,/VM/OpenBSD/obsd.img -c 4 -m 4096M -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd -s 5:0,ahci-cd,/VM/OpenBSD/install76.iso Router

Any ideas?

Thanks for help.

Best regards,
