as a final note, i've just switched the mobile sempron 3100+ (62W TDP) out for a turion mt-34 (25W TDP) for $15 off ebay. switching on performance governor for full 1800 MHz the turion temperature tops out at around 56C and does not get higher... which is almost the same as usual 800 MHz temperature for sempron! hopefully this ends the overheating issue. -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 22336] Re: CPU overheats during high usage throttling not supported
hi everyone i just ran into this overheating+shutdown issue with an amilo a1650 laptop, mobile sempron 3100+ (800, 1600,1800 MHz steps), gentoo 2.6.24 and 2.6.28-r10. in my case this was clearly a problem related to horrific thermal paste situation. afaik nobody has touched the cpu+hsf since the machine came from factory some years ago, but the cpu idle temperature was 56 C @ 800MHz. using performance or ondemand governor the cpu temperature would almost immediately skyrocket to 100+ C and the machine would almost immediately power off. before, this laptop had run windows xp for a almost 2 years now where it also exhibited some occasional freezes and shutdowns, although it would not do it so abruptly, and freezes also seemed to be related to which Mobility Radeon 200M IXP video driver i would use (the newer, the worse!). but overall it would be in a working condition, although you could visibly see (ProcExp) it would throttle to 800 MHz way too often and bog down any task which hogged the cpu for any period of time. yesterday i opened heatsink up and saw the thermal paste was in a terrible situation, as in it looked like nothing you would expect from a decent thermal paste application - hardened into pieces, scattered around the core, with random blobs stuck on the heatsink. applied some arctic cooling mx-1 and voila - it looks to have a worked. cpu idle temperature was 36 C after booting up, stabilizing at around 45 C @ 800 MHz after staying on for a while. i'm using ondemand governor, so 800 MHz is the usual working speed. in performance situations, the temperature does ratchet up double and more, but thanks to decent thermal paste, the fan has more time to kick in at higher speed and now the maximum temperature during 'make bzImage' was 98 C for a second. the cpu does get automatically throttled down to 800 MHz at high temperatures with performance governor, then switched up again at around 65-70C. i also and monitored and graphed it (attached). as you can see, these crappy low end laptops are just not very good performance or gaming machines. the cpu burns up easily and hardware has to scale back the MHz, killing any chance at high performance for extended periods. fortunately this one will do nothing sit idle most of the time with office work, so 800 MHz with occasional bump-up should work fine from now on. but obviously it's a worrying sign that coming out the factory, it was ill-prepared to do even that. googling amilo overheat is a clear indicator of that. ** Attachment added: graph of cpu temperature + mhz during make bzImage http://launchpadlibrarian.net/27519670/cpu.png -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Just to add another laptop model to the list: A Sony Vaio GN-FZ250FE. This laptop came with Window Vista, which runs the CPU significantly cooler than Ubuntu, the latter needing to use the cooling fan all the time because its temperature rarely drops from 55 Celsius. The NVidia GPU runs about 5 degrees hotter than the CPU, even when using Metacity instead of Compiz Fusion. I've seen this behavior in a brand-new Toshiba laptop too, but I don't have it near to check the model, and reading all the comments I realize any people have this problem too. When asked, it's kinda embarrassing to admit that Windows Vista is greener than Ubuntu 8.10 on many laptops. -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 22336] Re: CPU overheats during high usage throttling not supported
Actually, I don't know if 1 second polling is better.. Anyway, I am still testing this thermal module and what possibilities it gives me. Experiment is all i can do :-) Another note: for the first time power management works as supposed to in regards to battery reaching critical : now, it does what i told it to do, shut down the system cleanly. Previously, it ignored me and waited until battery went totally empty and then instantly hard-power-off. So, this new behavior is a good thing. Truly changing the trip points should be the goal. Newer kernels don't allow this i suppose. Thermal module's options say something about it..

[Bug 22336] Re: CPU overheats during high usage throttling not supported
Well, it turns out that after a reboot my good thermal state was all gone and i was back to shut down due to overheating - and my polling frequency was still polling disabled. I removed thermal module and modprobed itback again and things worked all right again, now my polling freq is back to 3 seconds. So, adding into /etc/rc.local the below lines did it or me: rmmod thermal modprobe thermal You probably cannot unload thermal because in your terminal you are inside /proc/acpi/thermal_zone directory. Get out and try rmmod and modprobe. Note: using this trick feels the right thing to do for my laptop. It just feels thermal behaviour is in its best state ever: for the first time i can see my cpu use all 4 scales (800, 1200, 2000 and 2200) of frequencies (for several minutes not instantly) where before it only scaled from lowest straight to highest (and stayed there on high load).

Thanks mplexus, surely I didn't care I was inside one directory created by the module. Now I have modified rc.local and polling frequency is set to 3 secs. I have tested it again with command 'yes | sha1sum' while monitoring CPU temp and freq, and freq raises inmediately 2GHz (max), and it shuts down when it reaches 100º (curiously, a message is shown on console that says it will shut down because it has reached 72º). Well, in my case polling is working fine, but I think it doesn't work because my trip_points file only contains 'critical (S5): 100 C', and the only event possible, then, is to shut down the computer. -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 22336] Re: CPU overheats during high usage throttling not supported
Hello everyone! My laptop is Acer 1524 WLMi with AMD64 3400+ (2.2 GHz). It surely suffers from shutting down due to overheating. I am using Ubuntu 8.10 64bit with default kernel 2.6.27-9-generic (yet the problem exists as many in this tread state from earlier versions). I clean the dust from the heatsink often enough and when I do it takes more time until the laptop shuts down from overheating - yet it still does shut down eventually. As I understand it has something to do with thermal trip points. I didn't compile my own kernel (as to fix DSDT errors etc). I use the on-demand governor (as default). These are the power-specific modules that are typically loaded: # lsmod | grep power powernow_k823684 0 cpufreq_powersave 10368 0 freq_table 13568 3 powernow_k8,cpufreq_stats,cpufreq_ondemand processor 47800 2 thermal,powernow_k8 # my /proc/acpi/thermal_zone/THRC has the following contents: # cat cooling_mode 0 - Active; 1 - Passive # cat trip_points critical (S5): 97 C passive: 90 C: tc1=2 tc2=5 tsp=300 devices=CPU0 # cat polling_frequency polling disabled # On-demand governor works fine - the cpu frequency varies from 800-1200-2000-2200 MHz up and down according to cpu load. The problem is that when reaching 90 degrees of cpu temperature the high-scale frequency should scale down a bit to let cpu cool off and then rise back up to cope with heavy load. This scaling down does not happen and critical temperature is reached shutting down the system. After reading Thomas Renninger's post, [Thomas Renninger wrote on 2007-04-25: ...The tsp value (time in 1/10s how often temp should be polled when passive cooling is on) can be overridden by passing as thermal module parameter. ...] I started to think maybe I should change thermal's module parameters. This is the output of modinfo thermal in my system: filename: /lib/modules/2.6.27-9-generic/kernel/drivers/acpi/thermal.ko license:GPL description:ACPI Thermal Zone Driver author: Paul Diefenbaugh srcversion: 1787CE9FEB053C917D031A9 alias: acpi*:LNXTHERM:* depends:processor vermagic: 2.6.27-9-generic SMP mod_unload modversions parm: act:Disable or override all lowest active trip points.

(int) parm: nocrt:Set to take no action upon ACPI thermal zone critical trips points. (int) parm: off:Set to disable ACPI thermal support. (int) parm: psv:Disable or override all passive trip points. (int) I edited my /etc/modprobe.d/options file and added options thermal tzp=30 act=0 crt=0 psv=0 The option tzp=30 means 3 seconds of polling, and as for the other zeros I thought they would let me override thermal trip points (I ave already tried manually overriding them by sudo -i ... echo etc only reaching to the conclusion that newer kernel doesn't allow it [ubuntu forums]). This was a heisty action just to see what happens. It turns out this has some good affects on thermal behaviour of my system. I created some CPU- consuming task ( yes | sha1sum ) and in a few seconds (must be 3..) after the THRC (cpu's) temperature reached 90 degrees the CPU scaled down to lowest freq (800MHz) for a few seconds giving the cpu a chance to lower it's temperature enough as not to reach critical point. After this brief break the cpu scaled again up to maximum freq (2.2 GHz) and I waited to see what happens when cpu temp reaches 90 again. Once again this happened, for a short period it scaled back to 800 MHz and then again to 2.2 GHz but it didn't shut down. I was bored and terminated the task - happy as ever that my laptop stayed alive! I am going to check again on that as days go by, but I wish this is the end of my problems! The polling frequency in /proc/acpi/thermal_zone/THRC now is set to 3 seconds (before it was disabled). All other numbers stayed the same (e.g. still not supported in cpu throttling...). In the past I tried to just echo 3 in /proc/acpi/thermal_zone/THRC/polling_frequency but the results where not the desired as it is now. As i said I probably make too quick a conclusion - we will see.. Anyway, I'm new to this forum and grateful I found this thread!

2.6.27-1-generic from kernel.ubuntu.com made no difference on my notebook. I tried both with polling disabled and with polling at 2 seconds, as set in /proc/acpi/thermal_zone/THRM/polling_frequency then ran a test with stress, and the temperature just kept climbing until it hit critical, which ACPI detected, shutting down the machine. The notebook (currently running Hardy, but the problem has been present since Warty): http://www.durbanet.co.za/colin/mecer-linux/mecer_n223ii_notebook_ubuntu_linux.html On machines like this, which don't raise an alert via ACPI at any temperature apart from CRITICAL, but which do have a constantly-updated record accessible via ACPI of what the current temperature is, is it not possible for the kernel to do the following: a. Poll the current temperature at a user-configurable period, with a reasonable default b. Turn on throttling or whatever else is required if the temperature goes above CRITICAL minus n, where n is a user-configurable value with a reasonable default. c. To turn off the protective throttling (or whatever) when the temperature drops below beneath CRITICAL minus n minus m, where m is user-configurable with a reasonable default. In the past, I've tried without success to achieve the above using powersave (which was not part of my Hardy install, so I haven't tried that again recently).

[Bug 22336] Re: CPU overheats during high usage throttling not supported
I did some testing today. I tried kubuntu 32 bit 8.04 - no luck. vmlinuz-2.6.25.5-1.1-vanilla kernel from suse 64bit worked beautifully. The system goes to 800MHz once it his 90C and stays at that speed until it cools down to 75C. The graph shows it nicely. The system did not shut down and this is very important. So we need to narrow it down to a specific patch. That is the list of suse patches http://www.mirrorservice.org/sites/ftp.opensuse.org/pub/opensuse/update/10.3/repodata/ . http://www.mirrorservice.org/sites/ftp.opensuse.org/pub/opensuse/update/10.3/repodata/patch-kernel-4749.xml --- looks particularly suspicious and would roughly fit the timescale.

I did some source comparison between suse and vanilla 2.6.25.5 kernels.
The ./drivers/acpi/processor_thermal.c and processor_throttling.c were
identical. Thermal.c were different (vanilla on the left):
[EMAIL PROTECTED]:~/Desktop/linux-2.6.25.5/drivers/acpi diff thermal.c

ACPI_THERMAL_TRIPS_EXCEPTION(flag, device);
}
} else {
tz-trips.passive.flags.valid = 0;
ACPI_EXCEPTION((AE_INFO, status, Invalid passiv trip
point\n));
I can't read this but hopefully this would suggest something. Especially
since thermal.c contains these lines further down:
/* take no action if nocrt is set */
if(!nocrt) {
printk(KERN_EMERG
Critical temperature reached (%ld C), shutting
down.\n,
KELVIN_TO_CELSIUS(tz-temperature));
orderly_poweroff(true);
}
Another point: THRC critical point on my system is 97C. 90C is PASSIVE, but I
get shutdowns at 90C. That may also mean kernel confuses CRITICAL with PASSIVE!

My T60p overheating problem with 7.10 appears to be solved. I did a BIOS upgrade to version 2.21 from the IBM/Lenovo website. Released 2008/02/13. http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovolndocid=MIGR-63027 The temperature skyrocketed when I ran a cpuburn test (up past 80C for 20 mins) but it wouldn't lock up. Minutes prior to the update, the machine would lock up in the 60-65C range. It also appears the fan is running about 600rpm faster by default. Verified by cat /proc/acpi/ibm/fan. I no longer have to physically set the fan to speed 7 anymore. This leads me to believe it wasn't solely a CPU temperature issue, as the machine can run MUCH warmer now without lockup.

[Bug 22336] Re: CPU overheats during high usage throttling not supported
I'm the owned of an Acer Aspire 1524 laptop, which suffers from this nasty overheating problem. I've gave up on running linux on it and now it runs windows exclusively, installed from the original Windows XP home that was bundled with the hardware. I've just reinstalled windows on that computer and, following my experience taken from that nasty job, I have to announce something to this group. Here it goes. This overheating problem isn't a linux bug nor a ubuntu bug. It's a hardware design/support problem, caused by the OEMs themselves and their majestic incompetence. Here's how I arrived at that conclusion. I've picked up the laptop, I've taken the windows XP install CDs, rebooted the machine, placed the first install CD in the optic drive and started reinstalling windows from scratch. After a couple of minutes into the installation process, the laptop hangs and then crashes. Due to overheating. The laptop crashed while attempting to install the original OS which came pre-installed and bundled with the hardware. Well, that could've been one of those rare crashes that only happen once in a while. I waited a while for the laptop to cool down and tried again to reinstall windows. Again, it hanged. Again, due to overheating. Now, that crash could also be caused by faulty hardware. So I ran the install process yet again, this time pointing a hair drier directly into the laptop's air intake. That meant spending about an hour holding a air drier pumping cool air at full blast into the laptop. The install process succeeded and I managed to reinstall windows on that computer. After installing a few applications and anti-virus, I noticed that the laptop wasn't displaying any problems, which seemed weird, following that nasty install process. To sum things up, I've installed a game (America's Army) and gave it a try. Well, the game played smoothly without a single incident for over an hour. In a computer which couldn't even pass the first 5 minutes of the windows XP install process without overheating. So it seems that's that. It isn't a linux problem after all. It's a hardware design and support, caused simply by the OEM's unlimited incompetence. -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Happy holidays to everyone. I also am experiencing this problem on my brand new Athlon 64 X2 with Biostar motherboard Ubuntu 6.06 LTS, 2.6.15-29-amd64-server. It is unusable at this point. I may have found the source of this problem: when the powernow-k8 module loads the following message appears in the messages log: Dec 23 22:21:35 flamingo kernel: [10705.713846] powernow-k8: Processor cpuid 60fb1 not supported. A search for cpuid 60fb1 at AMD's website led me to this page: http://www.amd.com/us- en/Processors/ProductInformation/0,,30_118_1260_1202%5E1073%5E871%5E13118,00.html which has a downloadable driver for kernels between 2.6.10 and 2.6.18. Since the kernel in this version is 2.6.15, it does not include the driver for the Athlon 64 chips, and requires this download. However, the instructions from AMD say to compile the kernel. I'm not prepared to do that, I only want to compile the module. I have the kernel headers because VMWare needed them to compile its module, and I wold like to compile only the powernow-k8 module.

Alex, this problem could be very machine specific and may be unrelated to the other reports. Please first make sure you are running the latest available BIOS and make sure your fans' performance match the needs of your CPU and are clean and not filled up with dust. Would you mind opening a separate bug at bugzilla.kernel.org against the ACPI component. Please post /proc/acpi/thermal_zone/trip_points and acpidump there. Also do a: cat /proc/acpi/events (you need to kill other applications accessing /proc/acpi/events first - fuser). Do you see (thermal or CPU related) acpi events when trip points are exceeded or if it gets hot? Does it work if you have only 1 process producing load? (E.g. if you compile a kernel with make -j6 it shuts down, but it works with just make?) There is an issue since some kernel versions, that it can happen, that an acpi event is not processed/ scheduled quickly enough to lower the frequency. -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 22336] Re: CPU overheats during high usage throttling not supported
Hi again! I have just reverted to kernel 2.6.20-15-generic (feisty) and this fixes the problem for me. During CPU intensive tasks (~100% CPU load) the CPU temperature peaks at 75°C but the system will not shut down. It seems that something got messed up (possibly in ACPI) between 2.6.20-15-generic and 2.6.22-14-generic. Suspend/resume does work again as before, so for now I will stick with 2.6.20-15-generic.

Hello all My laptop (Acer Aspire 5560) also suffers from this issue. A few instances of a script that does ls in an endless loop can bring my cpu temp to 95C. At that point it smells like melting plastic so I stop the scripts. Air vents are clean as a whistle, windows XP (it's a dual boot system) never gets close to that temperatures no matter what I run.

It's been two years after it was reported, yet this critical issue still exists. It seems to me that there are many people subscribed on this tread who will gladly assist in providing more debug info and beta test possible solutions. Can ubuntu engineers provide the reason for the fact this was not fixed by now? Also it seems to me that it should be mentioned here if/when this issue is expected to be resolved.

I have it on my desktop, it's doing great there and I wish I could keep it on my laptop (it's supposed to be for mobile systems as well, no?).

why cant you just Let the laptop use its Own built in auto fan control
as windows as far as i know norm does not control the fan under norm use
unless you loaded an driver or an program to control it, just looks like
Linux kernel ACPI or ubuntu is overriding the fan controls (and thermal
protection) when the laptop has working one and may damage laptop over
long time
i have an T60 laptop to test but i have to Bend it all the time to make it work
(looks like it was not put back together right missing screws {not me was given
to me}) i fix this laptop (pull it apart and rebuild it) and see if i can get
it working fine (boots into XP fine when laptop is bent lol)
if it overheats but Other Linux distros do not its an Problem with the Ubuntu

[Bug 22336] Re: CPU overheats during high usage throttling not supported
Gustavo, If your fan is clean and you can reproduce the issue on your T60 using the latest stable kernel.org kernel (currently 2.6.22), please file a sighting on bugzilla.kernel.org against ACPI. I don't expect to find ACPI fan control on the T60 -- as thinkpads have never had it before, but lets have a look. Please attach (do not paste) the output from acpidump to the report. Note that you should try with and without the thinpad/ibm_acpi driver loaded. Tim, 5024wlmi is an Acer, yes? Acer _does_ tend to use ACPI fan control, so we may have a fighting chance of doing something with that box. As above, please file sighting upstream. Also, to collect the output from acpidump, you may have to boot the system with acpi=off, which will likely enable some SMM-based fan control that will keep the system fans functioning properly. Michael, If p4_clockmod is necessary to keep a system cool, then the system either has some design issues, or failing cooling hardware. This is true also of using any other cpufreq frequency control. For a properly designed and functioning system should be able to cool itself sufficiently to sustain maximum performance as long as necessary. cpufreq may make the system run cooler on average, but doesn't address the case where the system is fully utilized where cpufreq does nothing. -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi i did post something about my now-almost-defunct laptop which was overheating. CPU was a pentium-m. in fact, it was overheating on feisty if i remember while previously (before an upgrade or update) it did not. I also strangly noticed that, at some point, the hard drive would lock and stop spinning- a feature that was not present on the actual machine- in fact the hard drive was heating so much that it was actually crashing -or call that a panic :P - . Since the PC had almost not the time to boot before to smell like something burning and crashing, i stopped using it. Recently i discovered that the hard drive was in fact intact and not overheating -through ide/usb interface- on a good system running the same version of ubuntu. More recently i decided to boot ubuntu from livecd on the dead machine. Didnt overheat, even when i wanted it to. i then plugged my hard drive to the usb port, installed ubuntu on it, updated No crash, no heat, nothing. My point is: i dont know if its kernel-package related, but somehow something blew my ide contoller up, or more likely has been driving my chipset crazy, the chipset running everything else -CPU ?- crazy as well. i recall that the cpu was changing its frequency all the time very fast (trusting the gnome applet). The thing that controls this is probably in the chipset (but i dont know :O ), and, is probably controlled by some sort of basic kernel driver or ACPI. Something overrides the normal, natural, BIOS- defined way of keeping the computer safe, or lies to the bios, or hte bios doesnt detect this stuff as an error and does its usual job driving the rest of the system crazy, making the box crash. -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Jul 4 22:08:18 unelma-laptop kernel: [ 1772.376000] ACPI: Critical trip point Jul 4 22:08:18 unelma-laptop kernel: [ 1772.376000] Critical temperature reached (80 C), shutting down. I did't have problems before. But after updating to edgy and now with feisty this have been very annoying problem. In XP I can use at least 15 wav-files with 15 vst-effects and still record a new track at the same time, without any warming. And XP has done shutdowns never (without user:). So this machine it's not a problem. In linux, I can listen hardly one sound file.. fun. I can hardly touch the underside of my laptop after shutdown, it's so hot.

My problem was due to Excesive dust in the airsink intake. You may wanna take a look. 2007/7/4, mikko sorri [EMAIL PROTECTED]: My Acer laptop does shutdowns at least once a week. It's not fun.

Alejandro, Mikko stated that he doesn't experience any overheating problems with XP.

[Bug 22336] Re: CPU overheats during high usage throttling not supported
For me - but my laptop has never overheated - just turning off powernowd lowered system temperature by 7-8 degree celcius (from 61 to 53 degrees idle - CPU T5500 still using ondemand frequency scaling governor). With powernowd system almost all the time ran on full speed, even if the CPU's weren't loaded with anything serious, thus ondemand governor was noot functioning properly - or rather powernowd broken it. Removing powernowd from init scripts fixes that problem, and CPU usually for text editing or web browsing are running on 60% of nominal frequency - so maybe bad powernowd influence on scaling governors causes overheating? Note - despite proper DSDT my T5500 has somewhat limited throttling capabilities: $ cat /proc/acpi/processor/CPU1/info processor id:0 acpi id: 1 bus mastering control: no power management:yes throttling control: no limit interface: no Stock ubuntu Fiesty with updated kerne everything else: Linux black 2.6.20-16-generic #2 SMP Thu Jun 7 20:19:32 UTC 2007 i686 GNU/Linux -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

/me too!!! I've only just started to encounter this issue as of this morning, despite having Feisty running pretty much since it was released. I'm going to give some of the above a shot over the next few days and I'll report back, just thought I should add my voice to this...

hmm... I escaped those shutdowns by commenting out all i2c related modules from /etc/modules (I suppose I added them myself previously, when trying to set up fan speed control). -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 22336] Re: CPU overheats during high usage throttling not supported
I was able to stop the shutdowns (at least for the last week, so far) by adding pci=noacpi to the boot options. But, I don't actually what that does or why it worked (or, what I lost by doing that). -- CPU overheats during high usage throttling not supported https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
