Don't worry about it -- that is sort of an exageration. In fact, it is your disk drive that will fry first:-) # CONFIG_ACPI_THERMAL is not set # CONFIG_THERMAL is not set Should be just fine, particularly for experimentation. In the case of a desktop system, ACPI_THERMAL is generally there just for processor throttling -- which would typically only be needed if you removed your heatsink or had some other serious cooling issue. And even if it is not there, a 2nd defense, the processor hardware thermal throttling would kick in automatically at a slightly higher temperature... -Len -- 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/
