Hi all,

I'm working with a board on which XEN panics with the following message (see below). From what I can see on the lists, most of the problems on these platforms seem to be related to broken DMAR tables and RMRR, but this platform passes the VT-d firmware toolkit (http://edc.intel.com/Platforms/Xeon-5500/) successfully so I'm tented to blame XEN for it... should I file a bug entry?

>From what I can see in the 'queue invalidation' code, a timeout is reached. As anyone seen this on a similar platform?
