Seems like this is a hang issue. So this is real hang like mouse also doesn’t work?

Anyway, there have two possible issues may introduce hang: the first possibility is related with scheduler bug with WALT, could you try the patch in the mailing list: https://lists.linaro.org/pipermail/eas-dev/2017-August/000944.html?

Another issue related with CPU power supply, could you try to update the latest booting image in the folder: https://github.com/96boards-hikey/tools-images-hikey960; you could see Guodong upgraded the booting images one day ago for fixing CPU power supply issue.
