I've been trying to sort out issues with my new Ryzen 7 Unraid build for the past 2 days and I finally got it running. I then attempted to get my VMs working by following spaceinvader one's tutorials. I was messing with IOMMU groups (I'm a bit ignorant on the subject) and changed the PCIe ACS Override to "BOTH". Upon reboot, Unraid will not start up (see attached). I wish I could post diagnostics but I am unable to type any commands. This has been an endless headache. Please help.

Wait 10min and try to login. Maybe you bind your gpu

Waited about 30 min. Server won't boot. I'm thinking about putting all of my old hardware back in.

Start your system in safe mode and undo the ACS override setting.

What was the solution ?

I am facing the exact same issue 🙄

Ok I found the solution

I put the USB key to my computer and I restored the file:

/boot/config/vfio-pci.cfg.bak to /boot/config/vfio-pci.cfg

You are a life saver. I'm having networking issues and figured I'd try upgrading the bios. I forgot to enable IOMMU, and unraid booted fine. After enabling it, it would not boot. I made this change, and I can boot back in. Thank you.
