Real suspend/resume support for AMD IOMMU is currently being worked on. Until this is ready it will be disabled to avoid data corruption when the IOMMU is not properly re-enabled at resume. The patch is based on a similar patch for the GART driver written by Pavel Machek. The overall driver merged into tip/master is tested with parallel disk and network loads and showed no problems in a test running for 3 days.
