List-id: List for Xen developers <xen-devel.lists.sourceforge.net>

While trying to track down the problem with booting Xandros, I got the attached data dump. This is the entire console session. Is this coming from Xen? I hope the attachment works in this list machinery. Didn't want to put this much text into the archive. The previous test got to: Warning: unable to open an initial console. ioperm not fully supported - set iopl to 3 warning: process `update' used the obsolete bdflush system call Fix your initscripts? The rest is the new data dump.
