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.
