Well, the console is not the problem (works as intended). It's raher the
IRQ's taht are getting mixed up. It seems it's doing twice a mapping of
IRQ (especially 9), once in XEN and once by the Kernel, which leeds to
ACPI failing and no network connectivity (see also start oft his thread
at
http://lists.xensource.com/archives/html/xen-devel/2010-01/msg01049.html;
somehow seems to got lost :-) ).

I did a lot of code study these last days, but I still don't really get
it... Nevertheless, I'd really appreciate if this could be sorted out...

Thx & regards,
Marcial
