Hi Christopher, There were no changes under the F11 ROM to the IOMMU issue under Fuduntu's 3.6 kernel as of two weeks ago. Also, I'm not currently running Ubuntu, so I won't be able to test the 3.8 rc4 kernel until I can make a little time for it, perhaps over the weekend. On Jan 21, 2013 8:20 PM, "Christopher M.
