Intel i350 nic causes Realtek onboard Ethernet to die

[zekemdm]

When I start unRAID VM service the onboard Ethernet goes dead.
 

I run pfSense on my unRAID server using a 4 port 1gb nic. I had a Realtek nic but it would become unresponsive so I swapped it out with an Intel I350 4 port nic. Now I can’t start the VM service running pfSense.

 

I believe it has to do with pfsense set to auto start and the current interface assignments not matching the hardware now. Previously I changed the assignments in the console but now I can’t get that far.

 

Could it be that my z590 motherboard onboard Ethernet is Realtek 2.5Gbe and the NIC is Intel I350 1Gbe? Brand compatibility issue?

I tried removing the binding of the IOMMU groups for the nic to enable the vm manager and unassigned the interfaces for pfsense, but with the 4 ports of the nic unbinded the onboard ethernet again went dark when I enabled the vm manager on unraid.

Delete/rename /boot/config/vfio-pci.cfg and reboot.

Thank you. Next time it occurs I will try this. For now I re-installed the RealTek NIC and it is working again.
