Thread-topic: [Xen-ia64-devel] RE: DomU can progress to xen_init from serialoutput
Oops, I forgot to add... in particular I am interested
in whether there are more ia64-specific changes to any
xen driver files, as I would like to work with Keir
to integrate the ia64 patches before the 3.0 freeze.

Thanks,
Dan
