Ensure CONFIG_OMAP_PRM is set while testing irq_chaining with uart. And for pm_qos usage ensure CONFIG_CPU_IDLE is selected other wise console might be sluggish.
There is console lag for omap2plus_defconfig given that CONFIG_CPU_IDLE is not enabled. Is the intention to force CPU_IDLE into the defconfig or find an alternative for the new pm_qos when cpu idle is disabled. Seen on beagle-xm and 3.3-rc1. Regards, Omar
