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...
