Adding Tom. Hi Joe,
My original patch was never accepted. Tom and Joerg worked on another patch series which was supposed to fix the issue in question in addition to do some code cleanups. I believe their patches are already in the mainline. If I remember correctly, one of the patches disabled PCI ATS for the graphics card which was causing the issue. Do you still see the issue with latest mainline kernel?

However, the patch never landed in mainline. There is a bug reporter in Ubuntu[2] that is affected by this bug and is willing to test the patch. I attempted to build a test kernel with the patch, but it does not apply to currently mainline cleanly. Do you still think this patch may resolve this bug? If so, is there a version of your patch available that will apply to current mainline?
