With a default boot sequence the machine crashes within a few minutes (typically less than 4), simply powering down without warning. Processor:AMD Athlon(tm) 64 X2 Dual Core Processor 5600+ Motherboard:Gigabyte GA-M55SLI-S4 (Rev 1.0) Drives:2 x WDC WD3200KS-00PFB0 21.00M21 (SATA 300GB) 1 x WDC WD10EADS-00P8B0 01.00A01 (SATA 1TB) The 300GB drives have been in use for some time one carrying FBSD 6.3 and the other FBSD 7.0. These have booted and run without problems typically with uptimes of months usually terminated by a mains power failure. Release 8.0 is installed on the 1TB drive. With acpi disabled the drives are not found so booting fails: normal for a relatively modern machine? I notice that sysctl for release 8.0 reports: machdep.idle: amdc1e machdep.idle_available: spin, amdc1e, hlt, acpi, whereas on earlier releases we have machdep.cpu_idle_hlt: 1 machdep.hlt_cpus: 0 Googling suggested there can be some issues with amdc1e so tried changing machdep.idle=acpi and later machdep.idle=hlt The system remained fragile. I had really expected that the "hlt" option would work. I now have machdep.idle=spin In /etc/rc.local #!/bin/sh echo "setting machdep.idle=spin" /sbin/sysctl machdep.idle=spin With this the machine stays up and runs without apparent problems. But the spin option seems to me to be a less than ideal workaround. I have used verbose boot with machdep.idle=spin and collected the following: # acpidump -dt | gzip > xi_home.asl.gz # gzip < /var/run/dmesg.boot > xi_home.dmesg.boot.gz # sysctl -a | gzip > xi_home.sysctl-a.gz Ian Smith has suggested that I post to this list and has kindly offered to host these as: http://smithi.id.au/mk/xi_home.asl.gz http://smithi.id.au/mk/xi_home.dmesg.boot.gz http://smithi.id.au/mk/xi_home.sysctl-a.gz Oh, yes I also have: hw.acpi.verbose=1 in loader.conf but suspect this may be too early in the boot sequence to be effective. With verbose boot I see messages: t_delta 16.043d7574c63ce4e0 too long t_delta 15.fbc6ac0df0853a80 too short t_delta 16.02e33b0b45fef6e2 too long t_delta 15.fd000012edba9452 too short t_delta 16.071c8a4c41eb266a too long t_delta 15.f8c6a8fa5f8dde0a too short t_delta 16.05b425c4a1d780d4 too long t_delta 15.fa4fe6f074261dba too short . . . Googling shows a number of reports of similar issues but I've not managed to find any explanations or even what t_delta represents. Your attention, thoughts and ideas will be appreciated.

I guess it might be a bios-issue too, this is a Lenovo t510 which seems to have a pretty screwed up bios so far.

I first installed and ran FreeBSD 5.5 without the error message. I recall that it began appearing after I switched from 6.2 to 6.3 and it still now that I'm running FreeBSD 8.0. I created an ASL file, looked at some of the code, and didn't notice anything obvious which might be responsible for the error message. I sort of got around the problem by adding: hw.acpi.thermal.user_override: 0 -> 1 hw.acpi.thermal.polling_rate: 10 -> 1800 hw.acpi.thermal.user_override: 1 -> 0 to a configuration file. It doesn't fix whatever causes the error, as the message still appears but not as often. I installed and ran FreeBSD on two different models of IBM ThinkPad without the error, leading me to believe that there might be an incompatibility between the ACPI code and the P5LP-LE motherboard. My question is whether there is a permanent solution to this or if the aforementioned quick fix will have to be sufficient? Any advice would be appreciated. Thank you.

However, as soon as powerd runs in and of the adaptive modes, the machine halts sooner or later, no matter what I try. If I don't run powerd, it works fine at a fixed CPU speed of 800 MHz, and it also works fine if I use powerd in "max" mode, which however corresponds to 2000 MHz CPU clock, and thus a lot of unnecesary fan activity. I tried applying the patches from either PR bin/136354 or PR bin/145063 (where 136354 is a little more flexible but with less obvious option names, otherwise both try to achieve more or less the same goal), and then limiting the CPU speed range, I tried setting debug.cpufreq.lowest, I tried changing the powerd evaluation interval, all to no avail. Even when I limit the CPU speed to a minimum of 800 MHz (where it runs fine forever without powerd), it will eventually hang. OTOH, without any limits, powerd is able to throttle the frequency down to 50 MHz without an *immediate* hang, it's just it will *eventually* hang. For example, limiting it to 800 MHz as the lowest frequency, it could sit for half an hour without problems, but once I started "periodic weekly" (thus rebuilding the locate database), it stopped working. That makes me suspect it's somehow a problem with actually *switching* CPU frequencies, rather than with any particular CPU frequency itself. As an additional symptom, whenever it jams, the fan is active, regardless of the previous CPU speed.

If this is satisfactory for whatever you were trying to accomplish, you can certainly stick to that. You can also dump your ASL (see instructions in the Handbook) and post it somewhere, i can grab it from. I could not promise you a fix, but if this is something easy like BIOS writer forgetting to multiply value by 10 or adding 2733 to it, you should be able to have normal thermal management. --- Alexandre Kovalenko. -------------------------------------------------------------- Ovi Mail: Being used in over 200 countries http://mail.ovi.com From owner-freebsd-acpi@FreeBSD.ORG Fri Apr 23 22:17:34 2010 Return-Path: Delivered-To: freebsd-acpi@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id CEE2D106566C for ; Fri, 23 Apr 2010 22:17:34 +0000 (UTC) (envelope-from avg@icyb.net.ua) Received: from citadel.icyb.net.ua (citadel.icyb.net.ua [212.40.38.140]) by mx1.freebsd.org (Postfix) with ESMTP id 13D5D8FC0A for ; Fri, 23 Apr 2010 22:17:33 +0000 (UTC) Received: from porto.topspin.kiev.ua (porto-e.starpoint.kiev.ua [212.40.38.100]) by citadel.icyb.net.ua (8.8.8p3/ICyb-2.3exp) with ESMTP id BAA13256; Sat, 24 Apr 2010 01:17:30 +0300 (EEST) (envelope-from avg@icyb.net.ua) Received: from localhost.topspin.kiev.ua ([127.0.0.1]) by porto.topspin.kiev.ua with esmtp (Exim 4.34 (FreeBSD)) id 1O5RBi-000Cd1-5Q; Sat, 24 Apr 2010 01:17:30 +0300 Message-ID: <4BD21C76.2040301@icyb.net.ua> Date: Sat, 24 Apr 2010 01:17:26 +0300 From: Andriy Gapon User-Agent: Thunderbird 2.0.0.24 (X11/20100321) MIME-Version: 1.0 To: Joerg Wunsch References: <20100423091710.GW69438@uriah.heep.sax.de> In-Reply-To: <20100423091710.GW69438@uriah.heep.sax.de> X-Enigmail-Version: 0.96.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Cc: freebsd-acpi@freebsd.org Subject: Re: FuSi Amilo 1667G stops when powerd is running in hadp/adp mode X-BeenThere: freebsd-acpi@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: ACPI and power management development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 23 Apr 2010 22:17:34 -0000 on 23/04/2010 12:17 Joerg Wunsch said the following: > dev.cpu.0.freq_levels: 2000/25000 1875/23437 1800/20900 1687/19593 1600/17500 > 1500/16406 1400/15312 1300/14218 1200/13125 1100/12031 1000/10937 900/9843 > 800/7900 750/7406 700/6912 650/6418 600/5925 550/5431 500/4937 450/4443 > 400/3950 350/3456 300/2962 250/2468 200/1975 150/1481 100/987 50/493 You seem to have far too many levels here.
