You've got a single critical trip point at 105C, but no active or passive trip points. Are you reporting some kind of failure? The only thing wrong with your system is that polling_frequency != 0 -- but that is probably a distro configuration issue rather than a kernel issue. thanks, -Len - 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
