Bhyve uses an io port range of [ 0x2000, 0x10000 ] [1]. At the moment, EDKII is using a subset of this range [ 0xC000, 0x10000 ] [2]. Even though the EDKII range doesn't exeed the bhyve range, it's causing issues on some guests like OpenBSD. We don't know why it's causing issues yet. However, using the same IO port range in EDKII fixes the issue and is a good idea anyway.
