Looks like a regression in the acpi subsystem or in power management, not hwmon. Hwmon is merely reporting the temperatures, it's not responsible for the actual temperatures. A bisection would certainly help, but of course that would require booting to a bad kernel half of the time, which I understand Manual wouldn't enjoy. The only two components which I think can reach such high temperatures in a laptop are the CPU and the GPU. I suppose that the "94 °C vs. 74°C" refers to acpitz's temp1? If the the temperatures reported by coretemp remain the same, then I can only suppose that temp1 is the GPU temperature. Please tell us which GPU is in this laptop, and which driver you're using. -- Jean Delvare SUSE L3 Support _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
