           Summary: Stubdomain freeze with 100% CPU offload on Windows XP
           Product: Xen
           Version: unstable
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: ar.fahrutdinov@xxxxxxxxx


XEN: 4.0.1-rc6
Kernel: 2.6.32.18 from Jeremy git

When I try to use network access from Windows XP guest without PV drivers, it
receives some packets and then freeze. Xentop shows WindowsXP-dm domain "eats"
100% CPU and message "+++++++++++ we have extras" has writes to log.

When I installs PV drivers, it drops the virtual iface from stubdom, and
problem disappears.
