My fault, since you have no chance to run into Xen or kernel.
I suspect it is the BIOS issue.
I am not sure whether it is convenient for you to downgrade the BIOS and
have a try.

I just want to confirm you don't have Azalia, because Azalia in some old
bios will enable the Isochronous VT-d table, which causes SINIT fails.
Forget this.

Right, you can see my output from Ross's dmardump utility at
http://docs.google.com/View?id=df2b4r7r_1hcbtgbnd
Or here is the binary output of acpidump -t DMAR. BTW you can see the
BEARLAKE chipset ID right there:
DMAR @ 0x3e2c225f
: 44 4d 41 52 98 01 00 00 01 ce 43 4f 4d 50 41 51 DMAR
Martin,
The dump utility I gave Hal earlier was reading the ACPI tables and
formatting/tracing out the DMAR table from his system. The DMAR is there and on
the surface it looked correct to me (at least nothing obviously wrong with it).
Hal attached the trace in an earlier reply.
Thanks
Ross

Hello Hal
I could be wrong, but I think what the "Enable VT-d" option in the
BIOS really refers to is whether the BIOS should set up the ACPI
tables related to VT-d.
You could use acpidump to see if those tables contain anything VT-d
related (DMAR and the like) - the VT-d spec would be helpful fo
Hello,
I grabbed the latest tboot using:
hg clone http://www.bughost.org/repos.hg/tboot.hg
In trying to build it, I get the following error:

I'm afraid these terms mean nothing to me. Azalia is something about
HD Audio? I don't know what that has to do with VT-d. Googling for
lsoc with VT-d or with Intel finds nothing relevant. And WA could
Hi Shane - I'm not sure what it would do to add these switches, since
tboot doesn't get as far as launching the kernel, since it hangs in
SENTER. However I can try doing it and then just booting into the
kernel, in case I get any error reports about VT-d.
Are there any MSRs or other registers I ca
I'm sorry, my Patch of lcptools.c wasn't proper. I found more missing checks,
here's my next try.

Hal,
If you work with Xen, please try to add "iommu=1 vtd=1" in Xen command
line (i.e. the end of "module /boot/xen.gz ...")
If you work with Linux, please try to add "iommu=on" in the command
