Dear Ralf,

I am also working on VT-d on Intel Desktop Board DQ45CB. We could share our
findings with each other.

Hi Pasi,

Sorry - I forgot to mention that I've tried setting the
iommu_inclusive_mapping=1 parameter too, but unfortunate I posted the output
from a previous attempt without this parameter.

The xm dmesg output and the DMAR parsing error remains the same. This was
the reason posting, because I ran out of ideas...

Best regards
Ralf Bonenkamp

Well did you try iommu_inclusive_mapping=1, like it suggests ?
