GPU Passthrough is crashing proxmox

I just grabbed an NVIDIA Tesla P4 for my R430 so I could pass through the GPU to my Channels DVR / Plex VM.

I followed this guide: https://hackmd.io/@u3-iFl9kQReVWgRWl65Img/HkBk_1Hza for setting up GPU Passthrough, and it works for a short time, but after about 1-2 minutes of using the GPU in the VM my entire Proxmox VE crashes.

I'm pretty new to all this passthrough stuff, so any help would be appreciated.

I'll try and include all relevant information below:

Bash:
$ pveversion
pve-manager/8.2.2/9355359cd7afbae4 (running kernel: 6.8.4-3-pve)

$ cat /etc/modprobe.d/*.conf
blacklist nvidia
blacklist nouveau
blacklist radeon

options vfio_iommu_type1 allow_unsafe_interrupts=1
options kvm ignore_msrs=1
options vfio-pci ids=10de:1bb3 disable_vga=1

$ cat /etc/default/grub | grep LINUX_DEFAULT
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt initcall_blacklist=sysfb_init pcie_acs_override=downstream,multifunction nofb nomodeset"

$ cat /etc/modules

vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd

Hello,

What do you mean by "crash"? Please provide system logs from the boot that crashed. It can be quite hard to know what happened without seeing the error message(s).
