GPU not visible/not found in system devices

[21cmal]

Hi guys, I have this device not found issue, my GPU is not found by Unraid.

Before this happens I passed through the GPU to a Linux VM and then since the VM was frozen I force stop it and I ran this user script:

#!/bin/bash
#
#replace xx\:xx.x with the number of your gpu and sound counterpart
#
#
echo "disconnecting amd graphics"
echo "1" | tee -a /sys/bus/pci/devices/0000\:06\:00.0/remove
echo "disconnecting amd sound counterpart"
echo "1" | tee -a /sys/bus/pci/devices/0000\:06\:00.1/remove
echo "entered suspended state press power button to continue"
echo -n mem > /sys/power/state
echo "reconnecting amd gpu and sound counterpart"
echo "1" | tee -a /sys/bus/pci/rescan
echo "AMD graphics card sucessfully reset"

It didn't complete and I kept it running for like a few mins and I just reboot my server, I think this is the reason why my GPU become not found by unraid.

 

Here is the vfio-pci log:

The device is stated not found and unable to bind device, I've tried reseating the GPU, rebooting, upgrading and downgrading the server but nothing works out so far... Could it probably be a BIOS or hardware problem? Anyone have experienced this before and maybe know the solution?

GPU is not showing on the system, are you able to test on another system or check power to it?

Thanks for your reply! Orignially it have no power but I swap the GPU to my Windows 11 system, then swap it back and it seems to work now. I don't know what happened but it does work fine now. Thanks!
