           Summary: unhandled page fault while initializing dom0
           Product: Xen
           Version: unstable
          Platform: x86-64
        OS/Version: Linux-2.6

        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: s@xxxxxxxxxxxx


There is an unhandled page fault while initializing dom0 on my host. I'm unable
to get the hypervisor running.

My config:
* Dual Xeon E5520
* Debian Sid with linux-2.6.32 (xen enabled,
http://packages.debian.org/sid/linux-image-2.6.32-trunk-amd64 ) with xen-3.4.2
( http://packages.debian.org/sid/xen-hypervisor-3.4-amd64 ) and grub2 (
http://packages.debian.org/sid/grub-pc )
* Bootable w/o hypervisor
