NIC port disappears after VM reboot

[RedSpider]

I am trying to set up pfSense in a VM for testing. Is fine on intial setup/installation but when i reboot the VM one of my interfaces (igb1 - LAN) completely disappears and can no longer be seen by pfSense.

 

 

I have a physical PCIe NIC (Dual Port Intel 82576) in my unraid box that i want to use for this VM and In my VM settings i have both ports selected.

 

So far the only fix seems to be I have to restart the entire unraid box. Any ideas/suggestions would be apprecaited and it's driving me mad trying to figure it out

 

Thanks!

 

Edit:
Noticed this in the terminal when a freshly installed VM rebooted
 

igb1:	<Intel(R) PRO/1000 82576> port 0xa000-0xa01f mem 0xc8c00000-0xc8c1ffff,0xc8800000-0xc8bfffff,0xc8c20000-0xc8c23fff irq 22 at device 0.0 on pci1
igb1:	Setup of Shared code failed, error -2
igb1:	IFDI_ATTACH_PRE failed 6
device_attach: igb1 attach returned 6

Edit 2:
Same thing happens with OPNSense

Replaced the NIC today, exact same issue. Nobody any ideas?

Looks like I managed to resolve the issue by swapping to a new NIC with I225-V chipset
