Comment 266 for bug 22336

Well, it turns out that after a reboot my good thermal state was all gone and i was back to shut down due to overheating - and my polling frequency was still <polling disabled>.

I removed thermal module and modprobed itback again and things worked all right again, now my polling freq is back to 3 seconds.

So, adding into /etc/rc.local the below lines did it or me:

rmmod thermal
modprobe thermal

You probably cannot unload thermal because in your terminal you "are" inside /proc/acpi/thermal_zone directory. Get out and try rmmod and modprobe.

Note: using this trick feels the right thing to do for my laptop. It just feels thermal behaviour is in its best state ever: for the first time i can see my cpu use all 4 scales (800, 1200, 2000 and 2200) of frequencies (for several minutes not "instantly") where before it only scaled from lowest straight to highest (and stayed there on high load). Cool ! :-)
