Arc Card not loading after reboot

[Host-in-the-Shell]

I have an Intel Arc A380, although under Debian 12. Sometimes, after a kernel update and a reboot, the GPU "disappears" too. What I do is turn off the server entirely and then power it back on. For whatever reason, the card shows up again. Is just one of those things that I haven't bothered to troubleshoot and correctly pin down why it happens, but for now, check if that fixes it for you.
