No, this is the second CPU fails to startup period. Giant isn't even a factor at this early stage. > The easy way to prove your thesis is to send a broadcast IPI.

At the moment I am getting an error after sending either the level-deassert INIT IPI or the first STARTUP IPI (if I disable the level-deassert INIT which is ignored by P4's anyways) of the type "Received Illegal Vector". I'm getting this error on the CPU that is sending the IPI however. :-/ [ irrelevant stuff removed ] -- 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-smp" in the body of the message
