Description Christian Trippe 2008-02-06 19:40:46 UTC

I have a Samsung P35 and tried to compile an Kernel because of bug 331011. During the make-process the critical temperature is reached and the system is halt. This is reproducable, I tried twice.

Does the smartd also read out temperature? Looks like the same temperature the ACPI thermal module reads. They may bite each other, confuse the thermal sensor and falsify the values.
Hmm, but the values still make sense (I'd expect unsane values like 3000 then).

Please, first make sure the fan slots are dust free!
Every second bug about thermal shutdowns is because of dirty fan slots.
Just using a strong vacuumer when the machine is switched off, could be enough. Sometimes you even have to open the machine to clean it.

Thanks for the hint to clean the fan slots. This has solved the problem. I had also stopped the smartd, but I hope to see no different behaviour with running smartd.

I mark this bug as invalid.

Sorry for the noise.
