Hello
I am running HiveOS on my mining rig & after a reboot; one of my GPUs is not being detected. The rest of the GPUs show up and mine as expected, but this one remains missing from the system. Running lspci | grep VGA confirms that the GPU is not listed, but it was working fine before the reboot. 
I’ve tried reseating the GPU, swapping PCIe slots & checking risers and power connections, but the issue persists. Could this be a HiveOS driver issue, a PCIe lane initialization problem, or something related to the BIOS settings? I’ve also checked dmesg logs but haven’t found anything conclusive. checked https://hiveon.com/knowledge-base/troubleshooting/-Azure guide related to this and found it quite informative.
Has anyone else encountered this issue? Would forcing a driver reinstall (hive-replace) or adjusting PCIe settings in the BIOS help? 
Thank you !!
