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.

Yes, I saw an email talking about a hang with cpuidle + omap4.

The thread is http://www.spinics.net/lists/linux-omap/msg99899.html

and the patch bringing the fix is https://patchwork.kernel.org/patch/3084521/

Seems the patch still is not in v3.13-rc3 kernel Any update for this issue?

Hope that helps.
