I still to have streamline my patch consolidation process, so your getting things like this as an artifact of that right now, sorry. That was the correct change. It might be the case that I need to remove some of that stuff and then reupload the patch. I'm kind of guessing at the problem right now with your stack dumps and it looks like the changes are causing more problems than it is helping. Let me change that and upload something else to you today. Your case is particularly difficult since I don't have a machine as big as yours that can replicate that problem and I can't do the normal kernel stuff that I want to on it. However, I do have a good idea of what the problem is and I'm trying to get reacquainted with the rt mutex code to see if I can narrow it down. bill - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
