Feb 19 16:11:22 jaques2 kernel: Critical temperature reached (46 C), shutting down. Feb 20 10:47:02 jaques2 kernel: Critical temperature reached (123 C), shutting down. Feb 20 10:47:02 jaques2 kernel: Critical temperature reached (44 C), shutting down. Mar 2 22:38:27 jaques2 kernel: Critical temperature reached (123 C), shutting down. Mar 2 22:38:27 jaques2 kernel: Critical temperature reached (44 C), shutting do this temperature always happens to be 123 C. How is that possible? I noticed that the acpi_thermal_critical method uses some kind of flag for enabled disabled, but apparently in any case the shutdown user space app (/sbin/poweroff) is called. Should this only be the case when the temperature is too high and the flag (enabled) is set to != 0? Otherwise, what is the point in the enabled thing. [tz->trips.critical.flags.enabled] As you can see from my kern.log, the second value is drastically lower, so could this be a weekness in the system, that one sporadically high value can trigger a shutdown? thanks -- Jakob ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
