Hi Michael,
After you change your BIOS's VT-d setting from Disabled to Enabled (or from Enabled to Disabled), can you try power cycle your host (unplug the power cord and wait for some time)?
If this works, it would be a BIOS issue.

 

Thanks,

Xen 3.4.1-rc8 iommu crash on Optiplex 760 ( Core2 E8400, Q43 / ICH10D )

Using the following build procedure from a clean amd64 debian lenny install

On an optiplex 760 with the latest bios (A03)

apt-get install ssh less bcc bin86 gawk bridge-utils iproute libcurl3 libcurl4-openssl-dev bzip2 module-init-tools transfig tgif texinfo pciutils-dev mercurial build-essential make gcc libc6-dev zlib1g-dev python python-dev python-twisted libncurses5-dev patch libvncserver-dev libsdl-dev libjpeg62-dev gcc-multilib git-core

hg clone http://xenbits.xensource.com/xen-3.4-testing.hg

cd xen-3.4-testing.hg

make world -j2 debug=y debugger=y

make install -j2 debug=y debugger=y

Xen boots without a problem if iommu is disabled but

if I enable iommu no matter the boot time parameters xen crashes as follows

And the second patch from the post (do not clear fault bits)

Gets us the following

(XEN) DMAR_IQH_REG = ffffffffffffffff

(XEN) DMAR_IQT_REG = ffffffffffffffff
