Do ACE tests > pass? Good question. I don't know. I wanted to try it at home in case I ran into other kernel panics, but I cannot compile. There's at least a problem with the mutex_d test, so I suspect that we still have some lingering issues. This does not look to be related to thread pointers. I don't know to what extend it will affect ACE. I think I fixed all of the kernel panics that were caused by using KSE on ia64, so I would suggest to try ACE on pluto1. The machine does not have the absolute latest libkse (aug 12) but it should be good enough for a first try. Note that pluto1 is building packages, so you're not on an idle machine. Please don't use pluto2 for now. It hasn't got the latest kernel... -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
