I am having these same issues with an 8.3-stable NanoBSD kernel I built. I tried it with and without all of the "depreciated" loader.conf variables like 'hw.pci.honor_msi_blacklist' Strangely, even copying in the kernel and virtio drivers from a known good system will not work. I still get the errors below. Suggestions on what else in the configuration might have an impact?
