Hello,
Somewhat new to the community and loving the product. I'm noticing a strange behavior on some of my Lenovo Tiny machines (could also be my Dell Optiplex but haven't noticed it there there). They're all M90q gen 3 systems with dual nvme ports and an additional sata ssd. Proxmox sees all of them with no issues. During installation, I choose to use a ZFS mirror with the dual nvme drives. The sata ssd disk gets chopped up into volumes as I need additional storage.

The problem I'm having is when these systems get rebooted, sometimes they come back right away and other times they hang on the Lenovo splash screen. I don't have access to the POST messages and haven't been able to figure out how to disable the splash screen so I can see them. It does seem to happen on multiple of the Lenovo nodes so I'm leaning more towards something I configured or did not configure vs. a hardware issue. All the disks and RAM are new and function perfectly fine once I'm booted into proxmox. The only issue I'm having is when there's a power outage and seemingly sometimes if I select the "reboot" button from the proxmox GUI/enter reboot in the proxmox CLI. It seems to be intermittent at best. All nodes are running vPro and are connected to MeshCommander but I've not yet been able to recover this condition via MeshCommander's remote desktop. I end up having to go to the machine and doing some combination of long pressing power buttons and unplugging power cables until the machine decides it's ready to boot again.

I'm not too sure where to take this one next. Has anyone else experienced this kind of thing? Any recommendations on where to take this next? Is it possible to get some meaningful log data from the hung POST or can I get rid of this splash screen somehow? Maybe I can then see what's happening.

Thank you in advance!
