Not sure if this would help: https://forums.unraid.net/topic/129027-intel-arc-support/?do=findComment&comment=1369821 Also check out the source where I found the solution for my case: https://forum.proxmox.com/threads/issues-with-intel-arc-a770m-gpu-passthrough-on-nuc12snki72-vfio-pci-not-ready-after-flr-or-bus-reset.130667/#post-573521 @Harmani Hope these would work.

I didn't use any custom kernel, just the default one with the Unraid OS release. Just hapenned to find a possible solution on the Proxmox forum, and it worked! Check this out: https://forum.proxmox.com/threads/issues-with-intel-arc-a770m-gpu-passthrough-on-nuc12snki72-vfio-pci-not-ready-after-flr-or-bus-reset.130667/#post-573521

The problems with ARC GPU passthrough also bothered me for quite a while (same "not ready XXms after FLR: waiting" issue). My issues: It is fine to simultaneously passthrough the entire card (video and audio) to a VM, no matter whether ReBAR is enabled or not. But on shutdown of the VM, "not ready XXms after FLR: waiting" is reported in syslog. After waiting for some time, "device inaccessible" is reported and I lost the card. I must hard reboot the machine to get it back. My server setup: MSI MAG B550M MORTAR MAX WIFI Intel ARC A380 index from GUNNIR AMD 5600G CPU Unraid Version: 6.12.4 ReBAR is enabled in BIOS. It can also be confirmed in a Win10 VM with the official Intel Arc Control software. It is solved by the following scripts (so I run them with the User Scripts plugin and set it to run "At Startup of Array"): #!/bin/bash echo > /sys/bus/pci/devices/0000:12:00.0/reset_method echo > /sys/bus/pci/devices/0000:13:00.0/reset_method Note that these scripts must be executed before the shutdown of VMs. Modify the physical address to your own case. I just need to run these scripts one time on each startup of the server, and I can flawlessly shutdown the VMs with perfect performance of the Intel ARC A380 GPU. No error lines are reported on logs. Not sure if this is what you need. It seems that with Linux Kernel 6.2+, compatibility issues are resolved, but I would just wait for Unraid offical releases because stability is much more important to me.
