Hello everybody,

i have an Intel i5-8600 with an UHD630 integrated.

I setup passthrough as followed

/etc/default/grup
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"

/etc/modprobe.d/blacklist.conf
blacklist i915

/etc/modules
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd

and since its a HP EliteDesk804 with only one descrete gpu

cat <<EOT >> /fix_gpu_pass.sh
#!/bin/bash
echo 1 > /sys/bus/pci/devices/0000\:00\:02.0/remove
echo 1 > /sys/bus/pci/rescan
EOT

chmod +x /fix_gpu_pass.sh
crontab -e
@reboot /fix_gpu_pass.sh


I have configured a Windows 11 VM as described in the wiki and when not using passthrough it starts flawlessly, yet once I pass it to the VM its stuck at the proxmox bootscreen

Can somebody help to trouble shoot this issue?
