Well, it does work. Right now if we enable multiple CPU's with SMPng the machine instantly panics, so we use a sysctl that keeps all the extra processors waiting until we are ready to kill the machine. Until that point in time, however, the machine runs happily on 1 cpu, and can build world ok, etc. -- John Baldwin -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.cslab.vt.edu/~jobaldwi/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
