No, crit_alarm stays set to 0 even when CPU temp hits 105. > Okay, That explains a bit of it. You have CPU cores and LCD registered as > cooling devices.

My CPU definitely throttles. When idling the CPU freq is 1.2GHz; when fully loaded it's 2.4GHz (according to /proc/cpuinfo) > AFAIK, The coretemp driver does not do/handle any hysteresis like this. > My best guess is again the BIOS has something configured to do like this. Oh yes, I should mention: the BIOS setup has an option "Fan Always on while on AC Power". I've tried booting with this option on and with it off but it appears to make no difference to Linux.
