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:
root@solidrun-imx6:~# echo mem > /sys/power/state
PM: Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.001 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done.
PM: suspend of devices complete after 49.228 msecs
PM: late suspend of devices complete after 0.914 msecs
PM: noirq suspend of devices complete after 0.908 msecs
Disabling non-boot CPUs ...
CPU1: shutdown

I use kernel with latest meta-solidrun-arm-imx6 commit rocko branch
`
SRCBRANCH = "solidrun-imx_4.9.x_1.0.0_ga"
SRCREV = "3b4f1a2b7c57f198641c0a45e23fe7255a164daf"
LOCALVERSION = "-mx6-sr"

SRC_URI = "git://github.com/SolidRun/linux-fslc.git;branch=${SRCBRANCH}
file://defconfig"`

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
