[Botao Sun <botao.sun@xxxxxxxxxx>]

Now this issue appears again. At the first time to run "lava-test run
pwrmgmt", I got this error:

LAVA: (stdout) cpufreq_07.1/cpu0: checking 'ondemand' decrease frequency
on idle...        fail

Then after reboot the board and run it again, system crashes.

Observed on Panda 4430 board with Linaro ubuntu hardware pack:

/hwpack_linaro-lt-panda-x11-base_20121001-349_armhf_supported.tar.gz

and rootfs image:

precise-ubuntu-desktop-20121001-452.tar.gz

The test works well and passed on Panda 4460 board.
