our new Server with AMD EPYC and super micro board reboots ramdonly. There is no error message before the reboot in /var/log/messages. we are running 2 Server with VMWare workstation without any problem. The new server should run KVM. older servers with AMD (before EPYC) running KVM without any problem. any idea or recommendation? -- Viele Grüße Helmut Drodofsky Internet XS Service GmbH Heßbrühlstraße 15 70565 Stuttgart Geschäftsführung Helmut Drodofsky HRB 21091 Stuttgart USt.ID: DE190582774 Fon: 0711 781941 0 <tel:+497117819410> Fax: 0711 781941 79 Mail: info at internet-xs.de www.internet-xs.de
