[Bug 404245] New: Acer laptop poweroffs intermintently after overheating
https://bugzilla.novell.com/show_bug.cgi?id=404245 Summary: Acer laptop poweroffs intermintently after overheating Product: openSUSE 11.0 Version: Final Platform: x86-64 OS/Version: openSUSE 11.0 Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: daugirdas@gmail.com QAContact: qa@suse.de Found By: --- Dear all, The problem was introduced in openSUSE 10.3 as a bugfix to one of the system files (probably kernel). The Original openSUSE 10.3 installation and all the previous 10.x versions ran perfectly fine, so does winxp 64 bit. To be honest I had the same issue with ubuntu ( [Bug 22336] ) and therefore switched to your product. My laptop is the notorious Acer Aspire 1522 WLMi, with AMD Athlon K8 3000+ processor and Nvidia geforce go5700 graphics card. I am sorry I haven't reported this before, as I had just a several crashes every now and then, but with 11.0 I ran into much more trouble. I presume there are some background processes which use much more CPU power? So today I just had facebook on FF on was on skype on KDE3 and it shut down just in 10 minutes. Yesterday it crashed when I had digikam on, and on the other occasion I just barely started gnome. Now it makes it unusable for me therefore it is major bug. My CPU policy is set on demand. "watch acpi -V" shows a massive hike in temperatures, which go uncontrolled up to 80C and there it goes. The setup was the only place where I used to have this problem before, went smoothly this time. [Bug 227360] If you need some technical information, please let me know and I'll do my best to get it for you. P.S. Well done with finally fixing the package management!

I've been successfully using my system with it in the past. As the system loads none of the remaining cpufreq modules are active (lsmod: cpufreq_conservative 26248 0 cpufreq_userspace 23556 0 cpufreq_powersave 18816 0 (If I select powersave in KDE battery applet a corresponding module shows 1) So it seems I am now running w/o CPU scaling. 2) dtrsuse64:/lib/modules/2.6.25.5-1.1-default/kernel/arch/x86/kernel/cpu/cpufreq # modprobe acpi-cpufreq FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.25.5-1.1-default/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko): Device or resource busy Would it be possible to get the ondemand module please?

You have ondemand built in to the kernel. Now, my system doesn't support throttling, but it does support scaling (1800, 1600 and 800 Mhz). I would be wise to make use of that. I suppose you could modify one of the powersave scripts for acer laptops (and similarly affected systems) so that you scale them down when they reach PASSIVE point. You had this working in the past anyway. I would happily do that but I really don't have the knowledge of programming. I am looking forward for the fix. Many thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The /drivers/acpi/processor_thermal.c and processor_throttling.c were identical. Thermal.c were different (vanilla on the left): daugirdas@dtrsuse64:~/Desktop/linux-2.6.25.5/drivers/acpi> diff thermal.c thermal.cs 443,445c443 < if (ACPI_FAILURE(status)) < tz->trips.passive.flags.valid = 0; < else ---

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! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Anyway your help is appreciated, I am sorry I missed track on this one. I removed the patch you showed up the differences in drivers/acpi/thermal.c in comment #7. It takes a while until the changes are built, put into upload directory and finally find its way to the ftp server. Also there is a lot other work to do, therefore I forgot about this one. A simple "ping!" would have been enough, though. The kernel is here: ftp://ftp.suse.com/pub/projects/kernel/kotd/SL110_BRANCH/i386/kernel-default.rpm (take the x86_64 directory for a 64 bit kernel). Please do not modify severity and priority flags. Priority is used for other things. I see that this bug should have high severity, but blocker doesn't make much sense after the product is out, the shipment can't be blocked anyway anymore. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I tried the kernel last night. Although I *think* I saw more freq scaling take place (mainly 1800 to 1600Mhz), once it hit 90C PASSIVE it quickly went overboard and powered off (on stock kernel it stayed at 800Mhz at that point until it cooled down by ~20C).

Be aware that trip points can change over time (this is seldom done, but HP for example makes use of it). watch -n1 cat /proc/acpi/thermal_zone/*/* should help to monitor what is going on nicely. I somehow doubt vanilla works and suse not, we do not have much extra patches. Hmm, wait: there is a similar strange report about suse kernel going wild and vanilla not, this could be related: bug #401740 This would make sense, can you check whether top shows something utilizing your CPU and therefore letting your machine running hot. This would explain why the culprit could be at a totally other place, not in the cpufreq/thermal area. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

PASSIVE disappeared once at 75C or 70C (I can't remember now precisely). When PASSIVE 90C point becomes CRITICAL for some reason all my problems start. Also it didn't scale to 800Mhz with suse kernel (maybe because it thought it reached critical, or maybe because the scaling clause was missed). #12: I am running the latest bios (April 2006).

I must admit my CPU burning methodology was wrong. zip doesn't use 100% CPU, hence the impression of scaling. Sorry for confusion. I ran gnome-appearance-properties [Bug 405154], and got a shut down with both kernels in less than 30s at 91C (passive displayed since 90C). So back to the issue. I believe it all started with suse after some update to 10.3 kernel. I have been just moderately using it, but I couldn't use ubuntu at that time at all due to this issue. I guess the best idea is to try 10.3 kernel and test any updates. How could I install that kernel ALONGSIDE 11.0 kernel?

Quite a few times CPU recovered from "passive" point, but finally managed to hit "critical". Maybe 5 could be replaced with 1 or 2? Or maybe better, could I set some custom powersave scheme, to say for example limit speed to 1600 (max is 1800) when temperature reaches {passive - 10C}, and only then slow down to 800?

Or maybe better, could I set some custom powersave scheme, to say for example limit speed to 1600 (max is 1800) when temperature reaches {passive - 10C} I demanded that in the ACPI kernel interface with no luck until now. Since passive cooling or say temp monitoring moves more and more to hwmon and userspace, I'll try again. But this is not trivial. Hmm, there should still be boot params to modify trip points. Does thermal.psv=60 boot param + setting polling frequency help?

The thermo gauge never reads above 50 but the laptop appears to be hard-hanging several times a week, instead of "never" or "rarely" beforehand. It appears to be temperature related. I will look into using some of the items above shortly. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

A list of affected machines could be added where polling gets activated, I try to bring that up. Until this may hit kernels (or if it does not get accepted), you have to add the thermal.tzp=10 (ten second polling should be enough) boot parameter. Best do that at installation time or add it in /boot/grub/menu.lst. Updating kernels will take over that boot parameter and everything works fine. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
