Yes, this is a Hardware issue for which the BIOS does not apply the
workaround. The only solution for now is to disable the IOMMU on the
Trinity based chips. Unfortunatly I don't have access to the hardware
any longer to write a workaround in the AMD IOMMU driver.
The question is what to do now, I tend to disable the IOMMU if a
Trinity chip is detected. This is not the first report of this problem
I encountered.

Joerg
