GPU passthrough issue

Hi all,

I'm having a weird issue with GPU passthrough.

Some facts:
- Proxmox 8.3.0
- Supermicro server with plenty x16 slots (built for GPU)
- 1 integrated gpu for the OS
- 4 x Nvidia 4070 TI Super (blower fan)
- 1 x Nvidia A1000

Now, the passthrough is working fine on 4 of the 5 cards.
Weird enough one of the 4070 cards is working only once when i start the vm.
If the VM shuts down i need to reboot the whole proxmox server to get output on the card.
All other vm's, the 3 other 4070 cards...
