    Kernel Version: 2.6.32
          Platform: All
        OS/Version: Linux
              Tree: Mainline

After a few day (but can be a short time), powernowd or the ondemand governor
doesn't work anymore. The cpu frequency can't be changed. I can unload the
longhaul module but, after modprobe longhaul fail (not found on my system).
I have to reboot.
