Hello, your setup uses Proxmox version 7.3-3 with OPNsense and NIC passthrough. Your hardware includes an AMD Ryzen 5 2600 ASRock B450M Pro4 (UEFI P5.70, current), 4x16GB Corsair Vengeance RGB PRO DDR4-3600 DIMMs, a 512GB ADATA SX8200PNP, plus SanDisk Ultra 3D 2TB, SanDisk Plus 2TB, and Mellanox ConnectX-3 10GbE and ConnectX-3 Pro. You've enabled SVM and SR-IOV but faced issues with IOMMU—repeated power cycles reset the setting. The ASRock documentation suggests upgrading past UEFI P3.50 isn't advised for your model, possibly pointing to a compatibility issue. Are there alternative fixes besides downgrading to an earlier UEFI version? Any other options you could explore? Thanks ahead.
