I would read the code in the wm driver and then find pci_intr_map, and see what debugging variables are defined, and build a kernel with them turned on. Then I would either figure out how to run kgdb or add printfs. I would also look at the demsg from FreeBSD and CentOS, and turn on any verbosity you can, and understand how the interrupt is mapped there. > With OpenBSD it's the same error. > I have no problems running FreeBSD or CentOS with the exact same setup. > > I realize that the problem is probably in bhyve and not in NetBSD, but is Could be either way.

My guess is that the bhyve code, as it was developed, was made to be enough like real hardware to get FreeBSD and Linux to work, and nobody has debugged the other situations.
