FWIW, I've tested a similar patch of mine a few days ago, because I'm having the exact same problem as everyone else in this thread on a bi-Xeon Intel motherboard. My patch just changes the start_ap routine to use a physical ID, and start_ap is called in a loop with CPU varying from 8 back to 1 until we get one processor started. It doesn't work. I even added additional delays in start_ap in case this would just be a timing problem, and it didn't work either. I'm not a SMP specialist (actually I was not subscribed to -smp until I found it searching "PHY FreeBSD panic y/n" through Google) so I have no idea what to try next. -- Pierre Beyssac pb@enst.fr To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
