No, I don't know what it is yet, but the "problem" is that when the SMP code tries to wake up the second processor, the second processor doesn't get to the right place to tell the first one that it started successfully. It may be that it isn't starting, or it may be that it is starting but is going off into lala land. -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
