I'm using a fresh install of FC3 on a machine that was previously running FC1 and later FC3T2 I'm getting ACPI induced shutdowns at an irritating frequency due to what looks like the wrong sensor being monitored watch cat /proc/acpi/thermal_zone/THRM/temperature shows indicated temperatures ranging from 22 to 60+ at random, and eventually it indicates a temperature over which the ACPI induced shutdown is called. What can I do to point the acpi software at the correct sensor on the motherboard? I have verified that the hardware is still good, and didn't fail during install, fans are still howling and cooling as I'd expect so it's definatly not that. I have also ensured that the machine is using the latest bios. It's a PC Chips M811LM ver 3.1 Here is one particular snapshot of the acpi info, and some salient points from kudzu.
