https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D222996 --- Comment #41 from commit-hook@FreeBSD.org --- A commit references this bug: Author: whu Date: Thu Jul 30 07:26:12 UTC 2020 New revision: 363689 URL: https://svnweb.freebsd.org/changeset/base/363689 Log: Prevent framebuffer mmio space from being allocated to other devices on HyperV. On Gen2 VMs, Hyper-V provides mmio space for framebuffer. This mmio address range is not useable for other PCI devices. Currently only efifb driver is using this range without reserving it from system. Therefore, vmbus driver reserves it before any other PCI device drivers start to request mmio addresses.
