Hi all. new to PROXMOX. here. I have a Proxmox server set up. I was able to get an RStudio Server instant up and running along with a MineOS server instance up and running. My Windows VM was running until I passed an NVIDIA RTX 3060 through. Now it hangs on boot. For hardware I have an Intel Core i9 10900k and an Asus Prime Z490 motherboard. Any and all help will be greatly appreciated

Otherwise, please show your iOMMU groups (in a readable way) and check the Syslog in the web GUI or
Some information about the system changes you made for PCIe passthrough and the VM configuration file (from the /etc/pve/qemu-server/ directory on the Proxmox host) will also help anyone to troubleshoot your issue.
BOOTFB occurs in cat /proc/iomem (run this command on the Proxmox host console after a reboot but before starting the VM) then you are running into a common kernel 5.15+ issue that can be worked around like this.Otherwise, please show your iOMMU groups (in a readable way) and check the Syslog in the web GUI or
journalctl -b 0 on the Proxmox host console for error messages that might give a clue about what is actually going wrong.Some information about the system changes you made for PCIe passthrough and the VM configuration file (from the /etc/pve/qemu-server/ directory on the Proxmox host) will also help anyone to troubleshoot your issue.
