I've got the same Issue under OpenBSD 5.9 and -current. 

The Interfaces:

For both interfaces under PPTDEVS and vmm loaded with bhyve:

Aug 12 02:31:20 aphrodite /bsd: em0 at pci0 dev 5 function 0 "Intel I217-V" rev
0x00pci_intr_map: bad interrupt line 20

Aug 12 03:44:15 aphrodite /bsd: re0 at pci0 dev 5 function 0 "Realtek 8168" rev
0x0cpci_intr_map: bad interrupt line 19

The CPU:

CPU: Intel(R) Core(TM) i5-4570S CPU @ 2.90GHz (2893.36-MHz K8-class CPU)

I also tried it on an actual iwm card:

iwm0 at pci0 dev 6 function 0 "Intel Dual Band Wireless AC 7260" rev
0xbbpci_intr_map: bad interrupt line 16
iwm0: can't map interrupt

The OS is 11.0-beta4 (but the same on 10.3).
