I assume you mean wakeup from system-wide suspend (echo mem > /sys/power/state)? Are you enabling UART wakeups? They are disabled by default, so you need to: echo enabled > /sys/devices/platform/omap/omap_uart.2/tty/ttyO2/power/wakeup It may work in v3.2 due to the fact that the UART runtime PM had the unintended side-effect of essentially disabling MPU and CORE PM. With that bug fixed and MPU & CORE actually hitting low power states, you'll need to ensure UART wakeups are enabled. If you're already enabling wakeups and this still isn't working, try adding 'no_console_suspend' to the kernel cmdline, try a suspend/resume and post the console output.
