--- Comment #35 from Vincenzo Maffione <vmaffione@FreeBSD.org> ---
(In reply to John Hartley from comment #34)

I found the issue, and you are basically right.
It's a PCI ID conflict between the QEMU PCI express root port device and the
netmap passthrough device. I must assume the PCIE root port is present in Q=
35
and not in i440fx, which explains why the issue only affects Q35.

I will disable the netmap passthrough devices until the proper support is
committed to QEMU.
Sorry for the inconvenience. I'll commit the fix tomorrow.
