Looking at the registers, I am pretty sure it is the D2D clockdomain that still has activity, but due to very poor Stacked-mode docs and no responses to the D2D questions asked to TI I have not been able to figure this one out. Help debugging this would be greatly appreciated. > Further doing a > echo -n 1 > /sys/power/sleep_while_idle causes a hang after the 5 odd secs > of UART inactivity. > Is'nt this option supposed to affect only the suspend path behavior? No, this affects the common idle loop, with and without CPUidle. > Is CPUidle disabled in the default defconfig now? > > 2) Suspend > echo -n 1 > /sys/power/clocks_off_while_idle > Hangs on a echo mem > /sys/power/state > Goes into suspend, but cannot recover I'm pretty sure all the hangs going into RET are related.
