What I'm really curious about is whether I'm the only one seeing this consistently- not the 1-3,5 above, but #4- where as soon as /sbin/init is invoked, the serial console has this repeated output that makes it unusable, period. I really don't want to debug this myself- I am *sooooooo* behind on other FreeBSD issues that I need to spend what few FreeBSD cycles I have on those. -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
