Adding the calls at the places you suggested solves the problem. Thanks. Which tree is feeding these changes to linux-next? How do I get this ia64 fix into that tree so it will go to Linus in the same merge that the changes that required this will be in? Do you want me to create a patch (I can do that, but I'm not sure that I can write a good commit message). If someone else does, then it can be marked: Tested-by: Tony Luck <tony.luck@xxxxxxxxx> -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
