I've configured gpio-keys as wakeup source, and tried to wakeup options in sleep mode:
1)with echo standby > /sys/power/state everything works ok
2) with echo mem > /sys/power/state, cpu stutdowns, but when I try to push button, current consumption increase from 100 mA to 350mA, but there are no reaction on the ttymcx0. After a while the board resets with reason :WDOG.
The log of the suspending:

I use kernel with latest meta-solidrun-arm-imx6 commit rocko branch

I'm not sure, but as I understand the problem may be connected wit hardware due to topic: https://community.nxp.com/thread/441037
So I use Hummingboard pro
Upd. I've went to last commit in this repository, without any progress in DSM resume
