Sorry, I've kind of dropped the ball on keeping up with this thread.

It looks like you guys have got the issue of identify the correct number
of physical interrupts and handling the APIC setup correctly etc in hand
but do we also need to consider taking the patch in
http://lists.xensource.com/archives/html/xen-devel/2010-03/msg00028.html
as well in order to ensure we have plenty of dynamic interrupts until
such a time as they can be fully dynamically allocated?

Ian.
