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

No, I was actually not enabling the UART wakeups.  But I tried it now
but it still doesn't work. :(

You definitely need that.

I have no_console_suspend in bootargs.  Without it, it didn't work with
3.2 either.

If you want to use no_console_suspend -- which is not recommended -- then 
you'll need 

http://www.spinics.net/lists/linux-omap/msg65786.html

but best simply not to use no_console_suspend.

Thanks, Paul! I was just chatting with Kevin about this on IRC.  With
your patch and no_console_suspend, it works. :)

I needed no_console_suspend because it wouldn't work otherwise on
<3.3-rc1.

Now I tried a vanilla 3.3-rc5 without no_console_suspend and enabling
the UART wakeup and it works fine!

Thanks for your help, guys!
