Hi, my hardware is an Shuttle SDS32G2 with E6300 Core 2 Duo processor, 2GB and GeForce 9800GS. Windows XP 64Bit operating systems runs stable with it. Fedora Core 6 with standard kernel (without XEN) only shows the first four lines during boot. You see the initrd... output and then nothing more happens. No Harddisc activity and so on. With Fedora Core 6 with XEN support, the kernel boots just fine and everything seems to go well. The behaviour with my Shuttle is reproducable with the first kernel at installation CD and the actual Update Kernel 2.6.18-1.2849.fc6. I need a stable environment. The XEN kernel made my desktop (Dell Optiplex GX620) very unstable. The Dell system wasn't stable while I worked in a X sessions. I don't need the Xen layer at the moment. Do you have any ideas? Bye, Thorsten
