PCI passthrough problem

[atka]

Hello I am trying to pass through a pci card through but get this for an error

[kvm: -device pci-assign,host=06:00.0,id=hostpci1,bus=pci.0,addr=0x11: Failed to assign irq for "hostpci1": Input/output error
kvm: -device pci-assign,host=06:00.0,id=hostpci1,bus=pci.0,addr=0x11: Perhaps you are assigning a device that shares an IRQ with another device?
kvm: -device pci-assign,host=06:00.0,id=hostpci1,bus=pci.0,addr=0x11: Device 'kvm-pci-assign' could not be initialized
/CODE]
I have enabled iomm and see this was an error in earlier versions of proxmox but haven't seen any thing recent about it.

Tried it in another slot? Sometimes it's a hardware limitation of the motherboard I believe.

What sort of card/device is it?

No there is only one PCI slot on the mother board and it is sharing the IRQ with one of my built in NICS and a PCI express based SSD and it is a soundcard. I have managed to do what I wanted in a container though so the problem is kind of solved for me.
