Throw a pr_warn() at boot only when CONFIG_CPU_IDLE is enabled. Note that it isn't enabled by default in omap2plus_defconfig. Also throw one when a suspend fails, saying bootloader *could be* a possible cause specifying the right version to be used.
In my view, these steps aren't sufficient, for the reasons described in http://marc.info/?l=linux-omap&m=135964568904053&w=2 Even with CONFIG_CPU_IDLE=n, it's still possible to attempt to enter full-chip retention idle on OMAP4 via 'echo mem > /sys/power/state', so it doesn't seem right to restrict a solution to that case. regards, - Paul
