I do see this stall on socfpga and on zynq, but in both cases the suspend mechanism is flakey in other ways, too. At least I can reproduce the stall sometimes. In your other mail you wrote that you test it like this: rtcwake -d rtc1 -m mem -s 3 But the stall appears only after 20 seconds. So the resume event after three seconds (-s 3) is getting lost, right? Thanks, Richard
