Sorry for the long delay with testing, but here come the results. I've rebased everything to 4.1-rc1 1. WFI + DeepIdle => freeze after approx: * 1 hours and 30 minutes, first test * 3 hours and 40 minutes, second test 2. WFI only (DeepIdle disabled via sysfs) => Still alive after 13 hours and counting The proper patchset will follow as soon as I figure out what change broke dns320l-daemon (The utility that speaks to weltrend mcu on ttyS1) It was working on 3.18.6, on 3.19 and up - it writes data to the port (and mcu acks it), but can't read any responses. Same thing happens to the python (pyserial inside) implementation of the fan-daemon: https://github.com/martignlo/DNS-320L
Andrew, did you realize that you request a non-standard UART baudrate in your python code above: port = serial.Serial("/dev/ttyS1", 115600, 8, "N", 1, 0.1) s/115600/115200/ Does that fix your communication issues?
