From mboxrd@z Thu Jan 1 00:00:00 1970 From: Myers Carpenter Subject: my kernel sez: "WARNING: unexpected IO-APIC, please mail to linux-smp@vger.kernel.org" Date: 25 Oct 2002 10:04:45 -0400 Sender: linux-smp-owner@vger.kernel.org Message-ID: <1035554686.26098.6.camel@trouble> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: List-Id: Content-Type: text/plain; charset="us-ascii" To: linux-smp@vger.kernel.org My kernel sez: "WARNING: unexpected IO-APIC, please mail to linux-smp@vger.kernel.org", so I'm doing so. Included is the first part of what I get running 'dmesg'. I hope this helps. My motherboard is a MSI KT3 Ultra2-R. This is a single CPU motherboard, but apparently with APIC.
