This is a Dual G4 1 gig Hz machine with 768 meg of memory. As for how to recreate this problem, I am not sure yet... All I know is that when editing a huge 20 meg or so text file in emacs, performance started to bog downand so I tried top in another window thinking that some cron job had started up and it reported only cpu0 and stated that it could not find/report on cpu1. I ran other tests but could not determine what the problem came from and so I eventually restarted and both cpus showed up fine then. I will try one more clean rebuild with test11 and this time enable interrupts to both processors and try to recreate it in a more controlled manner. I'll let you know if I find anything recreateable.
