No, not yet. There's just too much to do right now. For one thing: we cannot get to single-user or multi-user under ski. The init(1) process is started and I think it goes as far as starting sh(1), but eventually none of the processes gets scheduled and the idle loop just runs happily ever after... Once we've got that fixed, I can work on the SMP case under ski. I have a SMP capable ski ready to go for this. > This one is a 2 cpu Itanium box. Interestingly, the box never panics > outright. Yes. So far it seems we corrupt processes only... -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ia64" in the body of the message
