CPU Governor changing randomly?

    I've noticed my CPU governor will randomly change from ondemand to performance sometimes. I can't figure out what triggers this, nothing has root access that can change governor setting. I change it myself with echo cmd to modify /sys/devices/system/cpu/cpu0/cpufreq /scaling_governor.

    Anybody else experience this or have any idea why this may happen? It is completely random it seems, and happens without rebooting, just during use, or idle.

    Thanks.

    I changed permissions of scaling_governor to r--r--r--. That should prevent it from changing, whatever may have been causing that...  ???

    I don't know what the default system permissions for that file are supposed to be, but they were set as rw-rw-r--, all the other scaling files already were read only.

    If anybody has time to kill, and a fairly untouched setup as far as the governor goes, I'm curious what your '/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor' permissions are.

    We'll see how it goes.

    Thanks!
