Thread-topic: [Xen-devel] [vt-d][xen4-rc6] Hangs on startup 
This issue was reported last year in this mailing list: 
http://lists.xensource.com/archives/html/xen-devel/2009-05/msg00917.html
It turned out to be a BIOS issue.
Please update to the latest BIOS to see if the issue is still there or not. The 
link above also supplies a workaround patch.

Thanks,
-- Dexuan

Subject: [Xen-devel] [vt-d][xen4-rc6] Hangs on startup

Hi,

I'm trying to run xen4-rc6 with iommu=1 option, but it hangs during the startup.

When I run it with option iommu=0, it starts ok, and I'm able to run
HVM guests(didn't try PV yet).
I have Intel Q45 chipset on the motherboard so it should have vt-d
support. As dom0 I tried jeremy's 2.6.31 and 2.6.32 kernels.
The same thing happens on two identical machines. All vt and vt-d
options are enabled in BIOS.

Here is Serial Consol log:
