With 3 or 4 cpu's plugged in it crashes in start_all_aps() while attempting to start AP #2 (AP #1 starts up ok). The screen goes blank and the machine reboots without any messages to indicate the reason. >How-To-Repeat: Build an SMP kernel and attempt to run on any machine with more than 2 cpu's. I've only tried it on the SC450NX, but I believe it's a general bug. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
