Host Crash With NVMe Passthrough

Hi folks,

I am having an issue with my host machine crashing whenever I try to pass through 4 NVMe SSDs. All four of them are WD CL SN720 model drives.

I'm on an Asrock Romed8-2t Epyc Milan based motherboard, and the NVMes are all in separate IOMMU groups, with the slot they are in bifurcated x4x4x4x4. This is running Proxmox 9.

I have the problematic NVMe drives in the second PCIe slot from the CPU. I have four U.2 SSDs in the first slot that are also being passed through, but the U.2 drives work without issue. I need them all passed through because it's for a TrueNAS VM.

Can anyone point me in the right direction? I'm on mobile currently, but I'm happy to provide logs and additional detail when I can SSH into the machine.
