Proxmox server keeps on crashing

[fastest-snail]

My proxmox server (with i3 10100 CPU) keeps on crashing. I've 2 VMs (1 for NAS and one for media server) and a few containers. I followed a tutorial to split the integrated CPU and assigned it to media server VM. However, the whole proxmox keeps on crashing randomly. When I say crash, I can't access Proxmox web UI nor any VMs. After I connect the system to a display (using HDMI), it shows following message on screen.


Did I mess up while setting up the iGPU passthrough? How can I fix this?

Looks like you got a problem with your NIC which would explain why you can't reach the webUI or any guest.
And yes, if your iGPU is in the same IOMMU group as your NIC and you passthrough that iGPU, it would also passthrough the NIC so the PVE host would lose that NIC too. So don't start your VM with PCI passthrough and check your IOMMU groups with pvesh get /nodes/{nodename}/hardware/pci --pci-class-blacklist ""

This is what I get when I run

pvesh get /nodes/{nodename}/hardware/pci --pci-class-blacklist ""

How can I fix it now? I don't know what I am doing here, sorry if I sound dumb.

Looks like the iGPU got it's isolated IOMMU group.
