I have a PandaBoard > A4 which apparently has no trouble with the same kernel image. Which defconfig are you using ? Can you see if CPU_IDLE is enabled in your defconfig? I saw a similar failure on my panda es when CPU_IDLE is enabled. If this is the case for you please apply this[1] patch and give a try. Hope this helps. Let me know if you need more info.
