            Bug ID: 218113
           Summary: igb(4) panic on guest passthrough of i340
           Product: Base System
           Version: 11.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern

I've been trying to build a virtualised box with FreeBSD as a guest to do some
network stuff and I needed to passthrough physical NICs to the guest. I
attempted to passthrough a port of i340-T4 to FreeBSD guest, but this caused
panic at boot time: 

igb0: <Intel(R) PRO/1000 Network Connection, Version - 2.5.3-k> mem
0xe7a00000-0xe7a7ffff,0xe7afc000-0xe7afffff irq 19 at device 0.0 on pci4
panic: resource_list_release: can't find resource
cpuid = 0

This behaviour is consistent with both ESXi 6.5 and KVM (on Ubuntu 16.04.2)
hypervisors, yet when the same is attempted with Linux (Ubuntu 16.04.2) as
guest, everything seems alright.

The problem doesn't arise when the NIC is i350-T4.


For completeness:
