In July 2008 I reported a problem about critical temperature shutdowns: http://news.gmane.org/find-root.php?message_id=%3c87zlnyv14h.fsf%5f%2d%5f%40gismo.pca.it%3e Since I was not the only one experiencing it, reading the mailing list I had the impression it had been solved since then. And indeed I do not remember I have experienced it again. However, the last week it reappeared, probably because in the meantime I have not used my laptop at full power :-( Anyway, here we are: - I got 6 "Critical temperature reached (128 C), shutting down" experiences since January 30th - when I know that temperature could rise (e.g. using QEMU to build Debian packages for armel), I usually set the fan at maximum speed $ echo -n "level full-speed" >/proc/acpi/ibm/fan However, the last time (10 minutes ago) happened even with that setting and my setup was: * my usual Emacs session * Conkeror * a git-buildpackage process (basically building a Debian package from a Git repository and inside a chroot) * the Openmoko FreeRunner was plugged to the left USB port and charging * on one of the right port there was an Eutronsec SIMReaderCombo, basically an OmniKey CardMan 6121 USB SIM-sized smartcard reader coupled with a 2GB flash memory (in my case this is SLC, more information at http://www.eutronsec.it/ ) * the laptop is placed on a scientific laboratory desk and the airflow from the fan grid is free to circulate * the laptop is on AC power with no battery inserted - the last was on Debian kernel 2.6.28-1~experimental.1~snapshot.12674; since I am preparing for FOSDEM, I do not have time right now to test a vanilla kernel, but I will do starting from next Monday. Which kernel version should I test first, 2.6.28.3? That is all, I think. Feel free to ask for more inforation/test.
