Perhaps something is > writing some ports it is not supposed to? Nope. Your system is overheating, and on-board temperature sensors are complaining. Probably you should find whether lm-sensors have drivers for chips your motherboard has, and look at sensors output in that case... Maybe ACPI could report thermal zone as well, try looking at /proc/acpi/thermal_zone/* tree.
