hcook Posted December 20, 2020 Share Posted December 20, 2020 (edited) I have unraid 6.9.0-rc1 installed and running smoothly then IOMMU is disabled in BIOS, however whenever it is enabled it wont detect USB 3 ports but more importantly doesn't connect to my home network and instead connects to a weird IP and is not visible on network. Setup: ASRock B550 Taichi Razer Edition ATX AM4 Motherboard AMD Ryzen 9 3950X 3.5 GHz 16-Core Processor Unraid 6.9.0-rc1 HVM is enabled in bios, and bios is running the latest 1.3 from ASRock Attached is the syslog from diagnostics when IOMMU is enabled. However I don't know how to get the same thing when IOMMU is enabled and it won't connect to network (gets assigned a 169.254.*.* IP address) using the onboard NIC. I tried two different PCIE NIC cards to see if the NIC was the issue but had the same issue with the strange IP. USB 3 ports are also all disabled. I have tried amending the syslinux.cfg with multiple different iommu criteria like below, I tried both amd_iommu and iommu, as well as "pt" and "soft" for each and I still have the same issue. (this was the only solution I could find on google). label Unraid OS menu default kernel /bzimage append initrd=/bzroot amd_iommu=pt I need IOMMU enabled to be able to pass through my GPU to VM. I am not great at linux systems but can generally follow directions, if there is a way to get the diagnostic file when it doesn't connect to network please let me know, I also presume it would help but maybe someone knows if have the incorrect boot command or can try something different? I didn't have this issue on the Rog Maximus Formula VI. Maybe its just the motherboard? I could change the motherboard but there are limited options for one that has 8 sata ports (since I dont want to mess around with getting a SAS card yet, I have plenty of space on my 40TB setup) toxicserv-diagnostics-20201220-1922.zip Edited December 21, 2020 by hcook adding correct zip Quote Link to comment

hcook Posted December 20, 2020 Author Share Posted December 20, 2020 (edited) Thanks Squid. I enabled IOMMU in bios, booted up to the below screen (IP should be 192.*.*.*), and logged in. Updated OP to have the new diagnostic file. Edited December 21, 2020 by hcook Quote Link to comment
Squid Posted December 21, 2020 Share Posted December 21, 2020 Looks like you've bound some items for passthrough to a VM. Uncheck them all and try again (Tools - System Devices) Quote Link to comment

Uncheck them all and try again (Tools - System Devices) So I deselected all the items for passthrough, then deleted the VMs and turned off VM manager in settings, and still same issue. Diagnostics attached for this attempt. When I get home I think I will create a new USB with a fresh install of unraid and see if this is still an issue, since the last USB was from the previous intel build and and had VFIO-PCI Config plugin installed on it at one point, although its now deleted I cant remember if I did anything else in the settings previously. toxicserv-diagnostics-20201221-0826.zip Quote Link to comment
Squid Posted December 21, 2020 Share Posted December 21, 2020 Still present. Delete /config/vfio-pci.cfg from the flash drive. Reboot and retry Quote Link to comment

overt-lawmaker6885 Posted January 4 Share Posted January 4 (edited) Thank you for posting this. I was having the same issue with this motherboard ( ASRock B550 Taichi Razer Edition ATX AM4 Motherboard ). Deleting vfio-pci.cfg corrected the issue. I tracked down the topic using the google search term: unraid iommu eth0 not detected Hopefully the added keywords will pull this up for someone in the future.
