So it seems for me, that there is no driver which handles the temperature and the fan of the Acer Aspire One yet. A search on google didn't disprove it. That's why I started to write my own kernel module. But I tested it only with 2.6.28.4. Maybe there's already something in 2.6.29, not sure about it. > If the fan is controlled via thermal ACPI trip points, maybe latest kernel > versions do help? There were several commits lately in this area, e.g.: > 676962dac6e267ce7c13f73962208f9124a084bb > f5adfaa372c76423b6e8e4727a9701330374f364 Those patches have been applied to 2.6.28. > The latter adds a boot param you could give a try if you think it's worth it: > ACPI: Add "acpi.power_nocheck=1" to disable power state check in power > transition I will try the acpi.power_nocheck option, but google results on that don't sound very promising. --peter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
