We'll see how it fares. Hi, just a followup message. I'm now running the buildworld mentioned above, and the system is pretty much unusable. It exhibits the same symptoms as I have mentioned before, mouse jumpiness, bogus mouse input (movement, clicks), and the system is generally very jerky and unresponsive. This is particularily evident when doing things like webpage loading/browsing/rendering, but it's noticeable all the time, no matter what I am doing. As an example, the last sentence I wote without seeing a single character on screen before I was finsihed writing it, and it appeared with a lot more typos than I usually make ;) I'm running *without* invariants and witness right now, i.e. a kernel 100% equal to the SCHED_4BSD kernel. Best regards, /Eirik
