I can confirm the bug reported by eugenio. Same or very similar symptom here, running Ubuntu 11.10 64-bit with Unity on Samsung R710 notebook (only runs Oneiric with acpi=off boot option btw.) - The indicator just doesn't start but reports an error. Please see below.

Thanks in advance for looking into this.

So, I had this bug too. This happens when you disable "Cool n Quiet" from the BIOS in AMD systems (or if you enable HW thermal control, I'm not sure. I just have one AMD system, so I can't say much about other people...). When you do that, the file /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor will disappear, and the program will (obviously) not be able to find it, so it crashes...
I hope it helps.

Thanks for the info, Jose!

The Cool & Quiet setting on my BIOS is set to Auto, but it still crashes.

[Daniel Kessel (dkessel)]

I have this on a non-AMD system (Intel Atom 330)

Affects me as well on an Intel Haswell running on Ubuntu 13.10.

Same crash as the above, pretty much.
