[Xen-devel] No VT-d with Xen 3.3/3.4rc3 on Intel-Board DQ45CB

[Tim Kaufmann <tk@xxxxxxxxxx>]

Hello,

my system: Intel DQ45CB with latest BIOS (0079 as of April 6th 2009)  
and VT-d enabled, Core 2 Quad Q9550 (E0), 8 GB RAM.
Tested with OpenSuse 11.1, packaged Kernel/Xen 3.3 and kernel opts  
"iommu=1", "iommu=1 msi=1", "dom0_mem=1024M iommu=1", "dom0_mem=1024M  
iommu=1 msi=1". System freezes on boot, last messages displayed are
(XEN) I/O virtualisation enabled
(XEN) I/O virtualisation for PV guests disabled

Installed Debian Lenny and compiled 2.6.18.8 / Xen 3.4rc3 - same  
result as above.
I'd like to help debugging this, but I'd need someone to help me  
setting up Serial-over-LAN with one of my other computers (Ubuntu 8.04  
LTS, XP, Mac OS X 10.5).
Tim
