Hi. After h t t p s: // www .youtube.com/watch?v=z-q1WhZUICQ suggested pve 5.0 works out of the box on a C3000 based Atom system (they used a Supermicro platform) with eMMC, I tried my luck with the Gigabyte MA10-ST0 mainboard (h t t p s : //b2b.gigabyte.com/Server-Motherboard/MA10-ST0-rev-11#ov) Unfortunately I constantly get said error, and details show h t t p s: //i.imgur.com/nTm4tud.png However, the eMMC is ok, I tested it completely with dd, not a sign of i/o error. I'll try Debian for now, but it would ofc be nice if Proxmox would work "out of the box". edit: Debian 9.4 installed - went quite smooth. edit2: To clarify, I tried PVE 5.1 3rd release.
