Hello, I''m having a problem with a Dell server (PowerEdge 2850) and a recently installed Fedora Core 5 with Xen kernel (2.6.16-1.2096_FC5xen0). Whenever I try to copy a larger file (128MB) to the server over the network, the server crashes (register dump on the console, remote sessions stop responding). This happens consistently with Anaconda, Samba and WinSCP3. It has happened with yum twice, although it works most of the time. When I reboot the server with a kernel that does not include Xen (2.6.16-1.2096_FC5), the copying works. I need some help figuring out what my next steps should be. I don''t see anything unusual in the xend.log (see below). The xend-debug.log is empty. Is there some other place I should look? Are there any other diagnostic tools to use? Thanks for you help.
