Proxmox 8 AMD GPU Passthrough

[DarkJackal87]

Hello everyone,

i've been following the guide for the GPU Passthrough at this link:

https://forum.proxmox.com/threads/p...x-ve-8-installation-and-configuration.130218/

So far i've reached the part where i need to install the vendor-reset service, and i've installed it and configured the service which looks like it's running

○ vreset.service - AMD GPU reset method to 'device_specific'
Loaded: loaded (/etc/systemd/system/vreset.service; enabled; preset: enabled)
Active: inactive (dead) since Sun 2025-04-20 11:57:39 CEST; 3min 16s ago
Duration: 3ms
Process: 1520 ExecStart=/usr/bin/bash -c echo device_specific > /sys/bus/pci/devices/0000:0a:00.0/reset_method (code=exited, status=0/SUCCESS)
Main PID: 1520 (code=exited, status=0/SUCCESS)
CPU: 3ms

However, running the command dmesg | grep vendor_reset yeld no output and also running modprobe vendor-reset gives back:

modprobe: ERROR: could not insert 'vendor_reset': Key was rejected by service

I'm running latest Proxmox version 8.4.1, i can correctly passthrough my 2400GE iGPU to the Windows VM with error 43 currently, the first time the VM starts correctly but as soon i shutdown or restart it, the entire host crash....

Does anyone ahve any leads on this? Also secure boot it's enabled on the host

Thanks in advance and have an happy easter!
