Intel arc A310 ECO disappear after reboot

[Marraz]

I was using an Intel Arc A310 ECO to do transcoding but after rebooting my machine the A310 stop showing up in the OS (proxmox, lspci doesn't show the device anymore), it was a clean normal reboot, no changes in bios, just needed to remove a hdd. I try moving the gpu to other slots, test the gpu on another machine, updated the firmware using another machine with windows, tried enable/disable 4g decoding, resizable bar and sriov but no matter the combination it doesn't show up, tried enable/disable csm, tried removing devices, and even try other OS in the same machine with the same result.
Also check that it was connected correctly and in a clean port. 

It show again once when I reflash the bios and clear cmos but wasn't able to replicate anymore, no mare how many times I reflash and/or clear cmos is not showing anymore.

Also tried with a display connected but it didn't show anything

I'm booting in UEFI mode

Motherboard: ROMED6U-2L2T

CPU: AMD EPYC 7452

OS: Proxmox 8.3.3

Kernel: Linux 6.8.12-8-pve

Hi Marraz,

I'm getting back in touch to gather some additional information to help with the investigation. Please see below.

1. Which machine did you use for testing the graphics card, is it a known working system?
2. What operating system did you use during the testing?

I look forward to your response.

1. The machine I use to test it is a working system, nothing out of the ordinary, is a z690 motherboard with a I9 12900k CPU and use Windows 11 to test it
It worked just fine, I reboot a couple of times just to make sure and no problem, so I updated the firmware without an issue but once I connected again into the ROMED6U-2L2T it was the same, not detected at all
