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. >Fix: >Release-Note: >Audit-Trail: State-Changed-From-To: open->closed State-Changed-By: luoqi State-Changed-When: Mon Jul 12 17:12:48 PDT 1999 State-Changed-Why: Fix commited on 6/23/99 >Unformatted:
