Bhyve passthrough problems

[Mario Lobo]

Hello;

I'm trying to passthrough a firewire pci card to a windows 7 64 guest.

Without passthrough, the vm boots with everything working normally.

Here are my specs:

uname -a:
FreeBSD 11.1-STABLE #0 r328025M: Wed Jan 17 18:30:26 -03 2018
root at Papi.lobos:/usr/obj/usr/src/sys/LOBO amd64

PCI card (already attached to ppt0)

ppt0 at pci0:4:7:0:        class=0x0c0010 card=0x30441106 chip=0x30441106
rev=0xc0 hdr=0x00 vendor     = 'VIA Technologies, Inc.'
    device     = 'VT6306/7/8 [Fire II(M)] IEEE 1394 OHCI Controller'
    class      = serial bus
    subclass   = FireWire

Starting the vm with VNC:

bhyve -A -P -H      -c 4       -S       -s 0,amd_hostbridge       -s
3,ahci-hd,/Vmachines/disk.img,sectorsize=512       -s
4,ahci-cd,/Extra/Isos/Windows/Windows_7/null_dvd.iso       -s
7,passthru,4/7/0       -s 10,virtio-net,tap0       -s
11,fbuf,tcp=0.0.0.0:5900,,w=1600,h=900,wait       -s
20,xhci,tablet       -s 31,lpc       -l
bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd       -m 8G -H -w
WIN-764 
fbuf frame buffer base: 0xa42e00000 [sz 16777216] Assertion

As soon as I try to connect, the VM aborts with:

failed: (error == 0), function modify_bar_registration,
file /usr/src/usr.sbin/bhyve/pci_emul.c, line 491. Abort trap

Starting the vm without VNC:

bhyve -A -H -P      -c 4       -S       -s 0,amd_hostbridge       -s
3,ahci-hd,/Vmachines/disk.img,sectorsize=512       -s
4,ahci-cd,/Extra/Isos/Windows/Windows_7/null_dvd.iso       -s
7,passthru,4/7/0       -s 10,virtio-net,tap0       -s
20,xhci,tablet       -s 31,lpc       -l
bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd       -m 8G -H -w
WIN-764 

VM exits with:

Assertion failed: (mr->name == memp->name), function
unregister_mem, file /usr/src/usr.sbin/bhyve/mem.c, line 265. 
Abort trap


Same thing happens without "-A -H -P" on bhyve command line.

Would anybody have any suggestions on what else I could try?

Thanks,
