Comment 7 for bug 1185747

On Samsung Arndale board with Linaro Android build #447:

https://android-build.linaro.org/builds/~linaro-android/linux-linaro-arndale/#build=447

The board can't enter the suspend mode after time interval reached, with following error shows in serial console. However, the board is still alive after that.
