Hello!

I rode the "buy old enterprise for cheap..it will be fun" vibe and now I am currently unable to have my Intel Arc B580 passthrough to my Linux Desktop VM without crashing the entire setup. The VM is perfectly fine until I add the pcie passthrough.

Mobo: Supermicro X11DPi-NT
Ubuntu Versions tried
- Ubuntu 24.04.3 LTS
- Ubuntu Ubuntu 25.10

Steps:
Main guide followed: https://pve.proxmox.com/wiki/PCI_Passthrough#Introduction
Reviewed: https://forum.proxmox.com/threads/vm-gpu-passthrough-crashes-pve-host.125505/

Please help. I am about to erase my nvme drive and do a fresh install of Proxmox V9.

Edit 1: To add reddit link and Ubuntu versions tried
Edit 2: Before anyone says it, yes I bit off way more than i can chew but I want to learn shell, proxmox, self-hosting and linux skiills.
