I'm wondering if this thread is about something similar to a problem I've seen. My T61p often locks up when the outside temperature is high or when it is humid, and the CPU temperature is high (but less than 85C). Is this like the symptom you're addressing? -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
