           Product: Xen
           Version: unstable
          Platform: x86-64
        OS/Version: Linux-2.6
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: robert.nagy@xxxxxxxxx


Hi.

Here is a box with two quad core CPUs (E5410). I am trying with xen-unstable
because this is the only version that supports this CPU model (23).
I've spent a couple of hours trying to figure out what the problem is, but I
can't think of anything. So here is the crash and the kernel config I use.
