Actually, not just 5.2-R, but every version of FreeBSD that I've ever tried to install on this machine. Every time it goes to probe the clock chip, (i8254), the machine halts dead. I've tried to install with booting the floppies, with booting from CD, neither works. I've taken the drive out, put it in a different machine, done an install and put it back. Halts at the same place. I even went as far as flashing the BIOS to the latest one available from SuperMicro, still nothing. I've done some looking around with Google, and tried a few things (debug.acpi.disable, kern.timecounter.hardware knobs from the boot loader console), and nothing seems to work. Doing debug.acpi.disable="timer" allows the machine to boot further, but at a VERY slow pace, taking 20-30 minutes to do anything and then it hangs when the APIC is polled. I've been messing with this motherboard and pair of Pentium Pro 200s for the past 7 months (on and off), and now that I'm starting to make a little progress, it's becoming more of a thorn in my side. This machine isn't super mission critical, but now that I'm devoting some time to it, I'd rather not have the hardware beat me. *Grin* Any and all help is appreciated. --- Andy From owner-freebsd-smp@FreeBSD.ORG Fri Feb 13 00:16:11 2004 Return-Path: Delivered-To: freebsd-smp@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 55FBB16A4CE for ; Fri, 13 Feb 2004 00:16:11 -0800 (PST) Received: from briefzentrum.encephalon.de (encephalon.de [213.146.112.85]) by mx1.FreeBSD.org (Postfix) with ESMTP id F11C443D2F for ; Fri, 13 Feb 2004 00:16:10 -0800 (PST) (envelope-from rosi@encephalon.de) Received: from encephalon.de (stella.bytecamp.net [212.204.60.37]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (No client certificate requested) by briefzentrum.encephalon.de (Postfix) with ESMTP id 07B3E1DD49 for ; Fri, 13 Feb 2004 09:18:30 +0100 (CET) Message-ID: <402C87D5.5040509@encephalon.de> Date: Fri, 13 Feb 2004 09:16:21 +0100 From: rosi User-Agent: Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.6b) Gecko/20040212 Thunderbird/0.4 X-Accept-Language: en-us, en MIME-Version: 1.0 To: freebsd-smp@freebsd.org Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Subject: experiences using "options SCHED_ULE" X-BeenThere: freebsd-smp@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: FreeBSD SMP implementation group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 13 Feb 2004 08:16:11 -0000 hello, i know ... [/usr/srs/sys/conf/NOTES...] # SCHED_ULE is a new experimental scheduler that has been designed for SMP, but will work just fine on UP too. Users of this scheduler should expect some hicups and be prepaired to provide feedback. [...] ... so here is the feedback. We using FreeBSD 5.2.1 p2 on SMP machines (i386 / Dual-P3 / Dual-Xeon). These servers running Apache+Suexec+PHP+Perl+Python and nfs(4). We were curiously in the new scheduler and so we test it. After building and installing the kernel (the only! thing that changed was "options SCHED_ULE") we see the system takes much more cpu time. CPU time in % usr sys idl options SCHED_ULE 20-25 60-75 0-20 options SCHED_4BSD 30-35 35-40 0-35 Also we "see" much more suexec and php processes (usually, you can't see them because they are processed to fast ;) ) and the whole system felt slowly. On the search for the reason why the machine takes so much cpu time for system, we found 400% to 500% more interrupts on the NIC's(fxp/em). After building and installing a new kernel using SCHED_4BSD, the whole system runs like always. Very fast and well. If it is necessary, i would post more informations. But i think the "problem" is reproducibly on i386 SMP machines. Naturally we will also test the SCHED_ULE again, if something changed. --- Frank rosi@encephalon.de From owner-freebsd-smp@FreeBSD.ORG Fri Feb 13 08:06:04 2004 Return-Path: Delivered-To: freebsd-smp@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 4892816A4CE for ; Fri, 13 Feb 2004 08:06:04 -0800 (PST) Received: from mps5.plala.or.jp (c148240.vh.plala.or.jp [210.150.148.240]) by mx1.FreeBSD.org (Postfix) with ESMTP id 9D20C43D2F for ; Fri, 13 Feb 2004 08:06:03 -0800 (PST) (envelope-from e-kamo@trio.plala.or.jp) Received: from msvc2.plala.or.jp ([172.23.8.210]) by mps5.plala.or.jp with SMTP id <20040213160602.CJMO1808.mps5.plala.or.jp@msvc2.plala.or.jp> for ; Sat, 14 Feb 2004 01:06:02 +0900 Received: ( 5628 invoked from network); 14 Feb 2004 01:06:02 +0900 X-SVCK: Received: from unknown (HELO mpb1.plala.or.jp) (172.23.8.16) by msvc2 with SMTP; 14 Feb 2004 01:06:01 +0900 Received: from trio.plala.or.jp ([219.25.148.126]) by mpb1.plala.or.jp with ESMTP id <20040213160601.XSAQ29344.mpb1.plala.or.jp@trio.plala.or.jp> for ; Sat, 14 Feb 2004 01:06:01 +0900 Message-ID: <402CF61F.3000501@trio.plala.or.jp> Date: Sat, 14 Feb 2004 01:06:55 +0900 From: Eitarou Kamo User-Agent: Mozilla/5.0 (Windows; U; Win98; ja-JP; rv:1.0.2) Gecko/20030208 Netscape/7.02 X-Accept-Language: ja MIME-Version: 1.0 To: freebsd-smp@freebsd.org X-Enigmail-Version: 0.75.1.0 X-Enigmail-Supports: pgp-inline, pgp-mime Content-Type: text/plain; charset=ISO-2022-JP Content-Transfer-Encoding: 7bit Subject: differences between 4.9 and 5.x SMP X-BeenThere: freebsd-smp@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list Reply-To: e-kamo@trio.plala.or.jp List-Id: FreeBSD SMP implementation group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 13 Feb 2004 16:06:04 -0000 Hi, I'd like to know about differences between 4.9 and 5x SMP.

I don't have any suggestions, but my previous development machine was a P6DNF with 2 P6/200Mhz cpus and I don't remember having any problems with it (I last ran a pre-5.0 version of current on it, I think). -- Dan Nelson dnelson@allantgroup.com
