I will debug this crash. At this point, my concern is not about debugging this particular issue but whether to commit to our customers or not about the binary compatibility of FreeBSD X.0 drivers with all FreeBSD X.Y OS versions. I would like to stay safe and tell the customers to build the drivers on their respective revisions unless you folks think that the binary compatibility is maintained very strictly and this is one of those rare bugs. Please let me know. Thanks, Venkat.
