From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andreas Schenk Subject: An unexpected IO-APIC was found Date: Sat, 18 Mar 2006 11:23:11 +0100 Message-ID: <200603181123.11796.dr.andreas.schenk@gmx.net> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: Content-Disposition: inline Sender: linux-smp-owner@vger.kernel.org List-Id: Content-Type: text/plain; charset="us-ascii" To: linux-smp@vger.kernel.org Hi, although my kernel release is more than three months old, I dare to send this report, since it might nevertheless be of some value. I do not understand what it is about, though, but I do know a little about APIC. If it is not too much, please let me know, if this mail is of some value and -- if this is still not too much -- give me some explanation, or a link.
