Well, we don't really know anything about hungs you've been seeing or if it's the same problem each time. I'm comfortable the SMP kernel works with apt-get since I'm not able to reproduce the problem with either of the two SMP machines I have (PA8500 and PA8700). > I'm building with the change you mentioned now -- we'll see what > happens... > > OK.

But I may not be able to look at it until the end of the week. Try repeating with the kluged kernel a few times and see if it now always gets the same symptom (ie no HPMC). If it doesn't HPMC, most likely you need to run UP kernels until someone who understands cache handling and J5000 a bit can look at it. grant
