The motherboard I'm using is Abit BP6 with two celerons (it was popular back in 99). I'm running non-ecc RAM. While I try to reproduce it with a UP kernel and more reliable RAM, I have some indications on where some of these are coming from: I have a suspicion that in kern_mutex.c:510, if (td1->td_priority < td->td_priority) there may be circumstances in which td1 could be pointing to memory that has been freed. I've got a bunch of panics which result in kernel mode page faults at 0xdeadxxxx. -Arun > > > >Running on a dual celeron box. > > > >CPU: Pentium II/Pentium II Xeon/Celeron (367.50-MHz 686-class CPU) > > Origin = "GenuineIntel" Id = 0x665 Stepping = 5 > > > >Features=0x183fbff > >real memory = 201326592 (196608K bytes) > >avail memory = 191365120 (186880K bytes) > > > >FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs > > cpu0 (BSP): apic id: 0, version: 0x00040011, at 0xfee00000 > > cpu1 (AP): apic id: 1, version: 0x00040011, at 0xfee00000 > > io0 (APIC): apic id: 2, version: 0x00170011, at 0xfec00000 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message From owner-freebsd-smp Mon Jun 10 12:35:11 2002 Delivered-To: freebsd-smp@freebsd.org Received: from rm-rstar.sfu.ca (rm-rstar.sfu.ca [142.58.120.21]) by hub.freebsd.org (Postfix) with ESMTP id 9677A37B403 for ; Mon, 10 Jun 2002 12:35:01 -0700 (PDT) Received: from fraser.sfu.ca (vanepp@fraser.sfu.ca [142.58.101.25]) by rm-rstar.sfu.ca (8.12.3/8.12.3/SFU-6.0H) with ESMTP id g5AJYuTf001940 for ; Mon, 10 Jun 2002 12:34:57 -0700 (PDT) From: Peter Van Epp Received: (from vanepp@localhost) by fraser.sfu.ca (8.9.2/8.9.2/SFU-5.0C) id MAA24179 for freebsd-smp@freebsd.org; Mon, 10 Jun 2002 12:34:56 -0700 (PDT) Message-Id: <200206101934.MAA24179@fraser.sfu.ca> Subject: Athelon APIC problems?

I have a pair of Tyan Thunder K7X S2468NG Motherboards each with 512 Megs of ECC ram and dual MP1900 (1.6 Gig) AMD Athelon CPUs. Redhat Linux 7.3 (out of our beowolf cluster which is 96 nodes of dual Athelons) runs fine on both boxes. FreeBSD 4.5-Release runs fine on one of them and fails most of the time during boot on the other one. Our Linux expert told me there were a lot of problems with the APIC I/O support for the Athelons on Linux (and in fact he ran for a long time without APIC I/O enabled which doesn't appear to be an option on FreeBSD). He suggests that since it was intermittent that may be in fact what I'm seeing here and why one board seems to work when the other doesn't (as opposed to one board/CPU has a hardware problem). The vendor has swapped the Motherboard on the problem machine without effect. Before continuing to chase hardware problems (which may not exist) I thought I'd ask if there are known issues with Athelons. While I may yet just end up running Linux, the interest in FreeBSD is that under the netpipe benchmark, while speed under FreeBSD is much spottier than Linux (~650 Mbps against ~685 Mbps on Linux) CPU time is about half for Linux and only 1/3 for FreeBSD (implying more CPU time left for useful work on FreeBSD if it can be made stable).

Please see the release notes for the most recent Linux release, which describe somewhat what Linux changed in order to get around the problem. For a more detailed approach that you could then apply to FreeBSD, you will need access to the unpublished vendor Errata and/or to look at the Linux kernel source code VM system changes between the release that had the problem, and the release that didn't. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message From owner-freebsd-smp Mon Jun 10 19:15:19 2002 Delivered-To: freebsd-smp@freebsd.org Received: from rm-rstar.sfu.ca (rm-rstar.sfu.ca [142.58.120.21]) by hub.freebsd.org (Postfix) with ESMTP id 7A4D737B405 for ; Mon, 10 Jun 2002 19:15:14 -0700 (PDT) Received: from fraser.sfu.ca (vanepp@fraser.sfu.ca [142.58.101.25]) by rm-rstar.sfu.ca (8.12.3/8.12.3/SFU-6.0H) with ESMTP id g5B2FCTf008268; Mon, 10 Jun 2002 19:15:12 -0700 (PDT) From: Peter Van Epp Received: (from vanepp@localhost) by fraser.sfu.ca (8.9.2/8.9.2/SFU-5.0C) id TAA16860; Mon, 10 Jun 2002 19:15:12 -0700 (PDT) Message-Id: <200206110215.TAA16860@fraser.sfu.ca> Subject: Re: Athelon APIC problems?

At least I now know not to waste my time trying to make one box behave like the other :-). I'll see if I can find anything reasonable, but I suspect I'm out of my depth skillwise. I guess its either Linux or single CPU and may end up being single CPU. FreeBSD with kernel cruft such as ktrace and IPV6 removed does ~700 Mbps on a non SNMP kernel at about %30 CPU, the dual Linux kernel is using almost all of one CPU at a slightly slower throughput (of course it also then has the other CPU to play with).

My box being one of the slower MP boxes (366 MHz) with a small cache (Celeron) might be tickling some unusual conditions. The panics I reported are readily reproducible (I had trouble compiling a kernel or scp'ing one over remotely to that box). May be I did cvsup at an inopportune moment.

Got MSI 6321 instead and dropped in 2 Celeron 400's. I couldn't get smp mode to work properly w/ non-ecc ram. They ought to mention that ecc-ram is practically a requirement to run smp. That was my first problem. My 2nd problem was with the via 686 controller. I would get sync panics or something when running smp mode. Had to use a different ata controller. Of course, this was all way back in ver.4.2/4.3. Good luck! Hope you get things working before 4.6 gets released!

Here's my newbie SMP set up: Two 866MHz P-III's... One with the cD0 stepping and the other is a cC0. Intel's documents have informed me that mixing these steppings is ok. The mobo is a Asus CUV4X-D dualie. The SMP FreeBSD kernel runs like a charm. My only concern is when running dnetc (the distributed.net client) it can freeze the machine when chewing through its blocks (which generally lasts for few seconds when it happens) after which the machine will wake up as if nothing happened. If I run top before this occurs and wait for the machine to lock, top seems to wake up and the two dnetc instances look as though they're using 190+% CPU *each*. dnetc will continue to run properly until it is killed. Is this (relatively) normal with CPU-intensive programs like dnetc? I searched distributed.net's bug archive for SMP problems and only found a 'Bus Error' bug -- seems unrelated as it results in dnetc dying. I haven't been running dnetc since I noticed this happening and nothing else seems to cause this problem that I have noticed so far. Is this a symptom of something else? Could this be related to the mixed CPU steppings? Am I just being paranoid? Thanks, -Andrew PS. Below is my dmesg and mptable outputs respectfully. Copyright (c) 1992-2002 The FreeBSD Project.
