You can use kernel.old to compile a UP kernel. I always keep a UP kernel around just in case. Also, when did your SMP box become unstable? There was a known problem with SMP boxes when the vm page zero'ing during the idle loop was first turned on that has since been fixed with the latest commit to vm_machdep.c yesterday. Symptoms were frequent kernel panic 12's with interrupts disabled . -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
