I actually extracted the changes in the referenced commits from the vendor's current out-of-tree driver, and unfortunately he was able to duplicate the problem in his lab using that driver. As a workaround, Chuck, your reporter can boot with mem=3900 until the problem is resolved. I go on record with Chris: we should apply the patch at http://lkml.org/lkml/2007/6/25/293 until we get to the bottom of it. The patch is in Jeff's queue, but I think he suspects a driver bug and so far hasn't chosen to apply the patch. Jeff, can we ask you to please reconsider? Jay
