The following commit has been merged in the linux branch: commit 4de75cf9391b538bbfe7dc0a9782f1ebe8e242ad Author: Roland Dreier rdreier@cisco.com Date: Thu Sep 24 01:01:29 2009 +0100
intel-iommu: Make "Unknown DMAR structure" message more informative
We might as well print the type of the DMAR structure we don't know how to handle when skipping it. Then someone getting this message has a chance of telling whether the structure is just bogus, or if there really is something valid that the kernel doesn't know how to handle.
