I would expect an upgrade and reboot to make the CPU heat up. You would have to leave it idle for some minutes to make a proper comparison. If the temperature really stays higher with the newer kernel version then please install linux-tools-3.7 and generate a performance report: # running as root: perf record -g -a sleep 60 perf report -g > perf.txt Then send the report file perf.txt. (This report will list most commands running on the system, so you may wish to remove any sensitive information first.) Ben. -- Ben Hutchings Sturgeon's Law: Ninety percent of everything is crap.
