bhyve passthru windows

Windows loads normally without -s 7,passthru,0/20/0, but with it Windows 8.1 stuck on bootlogo, and Windows 10 shows me bsod with MEMORY_MANAGEMENT error. My bhyve script #!/bin/sh bhyve -c sockets=1,cores=4,threads=1 -m 4G -w -H -S \ -s 0,hostbridge \ -s 4,ahci-hd,win10.img \ -s...

I use FBSD 11.0 and VM port. When I try to use passthru, Windows crash at boot. bhyve.log (debug="yes"): Assertion failed: (error == 0), function modify_bar_registration, file /usr/src/usr.sbin/bhyve/pci_emul.c, line 491. fbuf frame buffer base: 0xa42800000 [sz 16777216] It is possible to fix?
