panda board es failed on cpuidle

[Alex Shi]

my panda board ES failed to boot up when I use omap2plus_defconfig + CPU_IDLE.
Is it a known issue or I missed sth in kernel?

CONFIG_CPU_IDLE=y
# CONFIG_CPU_IDLE_MULTIPLE_DRIVERS is not set
CONFIG_CPU_IDLE_GOV_LADDER=y
CONFIG_CPU_IDLE_GOV_MENU=y
CONFIG_ARCH_NEEDS_CPU_IDLE_COUPLED=y


kernel hang after the following output.
