On Panda 4430 board with Linaro ubuntu pre-built image:

http://snapshots.linaro.org/precise/pre-built/lt-panda-x11-base/299/lt-panda-x11-base-precise_ubuntu-desktop_20120909-299.img.gz

There are 2 ways can let board enter suspend mode:

1. Just wait , do nothing;

2. Click suspend from right top drop down list;

The first method works well; for the second method, the board can enter suspend mode successfully, but can't wake up, neither press F1 key nor click mouse, no any response.
