Thanks, just tried that. No luck. But then I changed ACS override from Both to Multifunction only and now passthrough of USB 3.1 controller worked! Still no luck with PCI card and another controller has unraid flash drive in it. Also upgraded to latest BIOS now and still working with multifuntion 🤷‍♂️ so could it be it was multinction all along?

SOLVED by using pcie_acs_override=multifunction only and not both (bios 3.90, unraid 6.8.3) working config: kernel /bzimage append pci=noaer rcu_nocbs=0-12 isolcpus=0-3,6-9 video=efifb:off pcie_acs_override=multifunction initrd=/bzroot rcu_nocbs=0-12 - unraid crashing fix for AMD video=efifb:off - disabling RX580 for unraid to be able to passthrough the only GPU to VMs Original post: Hi guys. Had Unraid for years and very happy with it. Plex, hackintosh, dockers. Using latest update now. Decided to go AMD for more cores... But, whatever I try I get "vfio-pci not ready after flr" in my unraid log when passing through any of three USB controllers I have. One is a ASM1142 PCI card. When I start VM it's won't come up (no image on monitor) and Unraid will become unresponsive which is extremely annoying as I have to hard reset I just changed my MB and CPU to ASRock B450M Pro4 and Ryzen 5 3600. Before I had ASRock Z270M Extreme4 and i7 7700K. I had no issues with z270m. GPU (rx 580) and USB controller passthrough worked well with ACS override. I usually don't post anything as I manage to find the solution myself but this one is confusing me. Below are my IOMMU groups. One with ACS override and one is without. I also tried 3 different BIOS versions. Using latest BIOS one USB controller (3.0) is in it's own group even but still having 1022 in it's id as most of the devices in my IOMMU. But no matter which BIOS version, group, vfio-pci cfg BIND method or in syslinux (as I had with Intel) I still et the same issue with VM won't start and Unraid hangs. I can't even attach usb devices to any VM as it goes to Pause state and I have to restart again. I also tried vfio attach plugin but my KB detaching after a couple of minutes and won't attach again unless I restart. In conclusion I wanted more cores to use MacOS and Windows VMs at once and got a headache instead Tried XHCI disable in BIOS, C-States, power supply idle setting, ACS enable (no EHCI handoff setting or other I found on forum) syslinux config: tried different cofigurations; video=efifb:off to attach GPU to VMs as I have RX580 only kernel /bzimage append vfio_iommu_type1.allow_unsafe_interrupts=1 pci=noaer rcu_nocbs=0-12 isolcpus=0-3,6-9 video=efifb:off initrd=/bzroot without overrides: IOMMU group 0: [1022:1482] 00:01.0 Host bridge: Advanced Micro Devices, Inc.

Hey, I know it's been almost a year but did you get that mobo? I'm having troubles with USB controllers passthrough on my ASRock B450M Pro 4

Hi @jwcolby54, what driver version are you using? I can't make my RX 580 working with Windows 10 VM. Black screen on driver installation and won't boot after that (tianocore and spinning wheel stuck). Tried a bunch of drivers with AMD Cleanup Utility each time... it's a pain, I'm literally dying rebooting so many times 😪 thanks in advance
