Hi, I have a server running bhyve in FreeBSD. I did PCI passthrough in order to have exclusive access to one of the network interfaces on the server. My plan was to use that NIC in OpenBSD. Unfortunately when I boot the 6.3 release installer I get this in dmesg: "em0 at pci0 dev 5 function 0 "Intel 82576" rev 0x01: couldn't map interrupt".
The installation goes through without errors, but the Intel NIC is not visible during install or after rebooting the installed system. Man pages suggest that the problem is a fatal initialization error. The NIC works without problems installing FreeBSD. In FreeBSD the NIC uses the igb driver. https://man.openbsd.org/FreeBSD-11.1/igb.4 The OpenBSD man page for em lists 82576EB as supported. The NIC is an Intel Gigabi ET2 quad: https://ark.intel.com/products/series/46841/Intel-Gigabit-ET-Server-Adapter-Series Could it be that the quad variant of the NIC is not supported by OpenBSD? Is there anything I can do to make it work? Is it possible to use the igb driver in OpenBSD somehow? Thanks.
