    DMA remapping


      Hi -- I'm playing around with the VT-d ACPI stuff and I'm noticing that when I turn on translation for the last DRHD (The one with INCLUDE_PCI_ALL), everything seems to halt the thread of execution and I'm not sure why.  The status of the root table, context entries, and page tables don't seem to matter and I can enable remapping on all the other DRHDs.  Any ideas why>
