Recently, when I reboot my Proxmox hardware, I’m greeted with this message after the bootloader splash screen. It won’t progress any further, even after letting it sit overnight.

But restarting it 5-10 times will eventually get past it.

I suspect it might have something to do with me passing a physical disk and the whole GPU to a Windows VM (my temp solution for TV gaming until I can get Sunshine issues ironed out) but I’m not sure where to start looking for the issue.

I thought it might be freezing when the VM tries to take control of the GPU, but with a continuous ping to both the server and the VM, I never get a response. That makes me think the issue is happening before the VM is started.

I’m basically just hoping someone could point me to a log that might have a related error message.
