I guess shorten the polling time or setting a bigger hysteresis might help. I'll try and report back.

Therefore the passive polling interval, wich is 1 min on those came in and the machine of course shut down, maybe there still is something like that, or if the machine is quite busy, it's not a real second when the polling happens...). Also without polling the machine will always shut down, because it only throws an event for the critical, but not for the passive trip point -> Robert with great luck they fixed this up in a BIOS update, can you search for one, pls. The interface to override the passive trip point disappeared -> adding Len and ACPI people to show the need of a passive cooling interface. I want to work on a general passive trip point interface, easy to lower by users, but didn't have any time to even look at this. Hmm, even the kernel passive trip point solution works very well, maybe this should/could get programmed in userspace, lowering max_freq would allow this even with ondemand governor -> adding some people who should know about this to get some input for a userspace solution. Not sure what we should do here now, thermal shut down is critical. We should first look why it shuts down with thermal polling enabled (did this work reliable with 10.2 or have you already lowered passive trip point there?) and search for a general bug. We could then start a blacklist and enable thermal polling on specific machines or go back to general thermal polling. -- 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.

https://bugzilla.novell.com/show_bug.cgi?id=333043#c9 --- Comment #9 from Robert Simai 2007-10-16 05:41:40 MST --- I did not load sensors modules or anything else actively. I unloaded the modules from your list without problems and checked they are gone. I monitored the temperature and state and put some load on the machine. BTW, I tried this with 0 (default) and 2 in /proc/acpi/processor/CPU/throttling The machine shut down, same behavior as before. But there was an interesting observation: Temperature increases until it reaches 90°C, it switches to PASSIVE and the CPU is throttled from 1700000 to 1200000. Once it stayed in this state even if temperature went down to ~65°C, then I needed to take away the load so that PASSIVE switches off. Most often PASSIVE switches off already at ~85°C. If the latter happens, temperature starts to swing around 90°C for a while and the system reproducibly goes up beyond 93°C and shuts down. FYI: I also put the modules from Comment #8 to /etc/init.d/blacklist, hwmon and thinkpad_acpi were loaded anyway. It really seems to be a much too small hysteresis 89-93°C for the thermal design of this laptop so I'm looking forward to have a possibility to set the trip_points again, in whatever way.

I did not load sensors modules or anything else actively.

The vendor-specific ACPI modules are loaded automatically by /etc/rc.d/acpid, this includes thinkpad_acpi.

FYI: I also put the modules from Comment #8 to /etc/init.d/blacklist, hwmon and thinkpad_acpi were loaded anyway.

I remember similar results with other modules loaded by the init scripts. For some reason it seems that blacklisting doesn't work in this case, and I consider it a bug. -- 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.

Yes, sorry for the confusion. T42 shares the same BIOS as T41 but generates an ACPI event for the passive point. Andreas, maybe you like to try this with your R50?

Yes, sorry for the confusion. T42 shares the same BIOS as T41 but generates an ACPI event for the passive point. This is interesting. In this case it may be worth to compare the EC firmware (which you should be able to download from the ibm site and flash separately) between those machines. If you have a look at the dmidecode info you provided, this string states the EC firmware version. Maybe they really fixed it up in the EC firmware (does the T42 also shutdown?):

So you should look out for an acpi event (via acpi_listen) like: CPU 00000080 00000004 (limit frequency to the lowest, if 4 freqs are provided) CPU 00000080 00000000 (allow all freqs again) This also explains Robert's comment #43 (I unset the private flag for it..), where he states that it happened that the CPU got limited to the lowest frequency which does not come from the passive cooling interface, but from simply lowering the freq to the lowest by BIOS. The mechanism itself works. I tried with one process producing CPU load and could not get the machine to shut down. I expect that if you do a "make -j4" if you compile a kernel or you have several CPU intensive tasks, it takes too long until the thread to lower the CPU is scheduled. So I expect we have priority/schedule issue here.

So we probably do not want to fiddle with scheduler/priority code in ACPI parts, this would be much too dangerous for 10.3. What is totally weird is that another T41p I had, was not that hot at all and it was impossible to reach higher degree C values than 80. The same machine (not model, but the same machine) was reported to reach these high freqs like on Robert's (also a T41p). It looks like there is an offset of 10 or 20 degrees added (starts at about 40 degree C when it's switched on, the other one I looked at (Thomas Siedentopf's) started below 30 when I had it. The AML code is pretty easy and there is no bug in AML. Maybe a kernel with the latest "check for acpi interference" could reveal something... Only thing I could imagine is that we have again some very strange EC mess up, (similar to the psmouse module on some HP nc/nx series) some time ago, where even reboot did not help, because the EC firmware could hold it's broken status over reboot/shutdown. However, this might even not be debuggable in OS, maybe by bisecting... Someone who still has a Windows on his machine could have a look whether after booting Windows and 10.3 again, the temperature starts at lower values (just an idea...) IMO we should blackilst the machines and lower passive trip points there for 10.3 for affected machines, and close this one. I added a patch now to blacklist T41, T41p, T42, T42p, T43, T43p and R40 ThinkPads to lower passive trip point by 10 degree C and activate thermal polling with a frequency of 7 per second.

I've tried with this kernel, including your blacklist patch. Sometimes when putting load on the machine the temperature jumps up to 92°C (critical is 93°C!) before the CPU is throttled.

I already had two "controlled" shutdowns (kernel: Critical temperature reached (93 C), shutting down.). While I find * Mi Feb 06 2008 - trenn@suse.de - patches.arch/acpi_thermal_blacklist_add_r50p.patch: Avoid critical temp shutdowns on specific Thinkpad R50p (https://bugzilla.novell.com/show_bug.cgi?id=333043). in kernel 2.6.22.17-0.1-default changelog on 10.3 I can't find anything like that for kernel 2.6.25.5-1.1-default on 11.0. Thomas, maybe the patch didn't make it into this one? -- 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.

Interestingly, the 'thermal.psv=80' boot option does NOT fix the problem for me, although it does actually change the trip point. After setting the boot option, I get (as expected I think): cat /proc/acpi/thermal_zone/THM0/trip_points critical (S5): 94 C passive: 79 C: tc1=8 tc2=5 tsp=600 devices= CPU But - the temperature still goes far above 80C when I run a CPU intensive task - and it does not scale down the CPU to a lower frequency at all. Pavel, the problem was fixed in OpenSUSE 11.3 kernel by Thomas, but I do not think the patch made mainline... The only fix that ever worked for my laptop was the blacklisting patch for thermal.c. cheers Niel -- 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.

Interestingly, the 'thermal.psv=80' boot option does NOT fix the problem for me Sorry, simply reducing the passive trip point does not help, you also need to tell the kernel to check for the temperature, also adding a polling interval in 1/10 seconds should help:

I just tried using thermal.tzp again, and it actually does work eventually. It's just that with the tasks I ran, the temperature still went to 86 or 87C before it scaled down to 1200 MHz. I thought thermal.tzp=80 means it would detect the high temperature after 8 seconds... it seems longer to me though. My OpenSUSE 11 migration went fine without any of this. I totally share you opinion about this requiring attention. I'm not sure why the bug status is RESOLVED - isn't this a regression from 10.3 now? These Thinkpad models have not ever had proper thermal support and they're about 5 years in their life cycle - apart from the fix you managed to merge in the last OpenSUSE 10.3 kernel. I actually don't mind adding command-line parameters to the kernel, but I also think it would too much to expect the same from a non-technical user.
