Ikos Systems
>Environment:
4.0-19990604-CURRENT #18: Fri Jun 18 12:24:40
Intel SC450NX
>Description:
An SMP kernel with 2 cpu's works fine.  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.
