Hello Team,
We are working on a product based on DB410 and working on Linaro-18.01 platform.
The described kernel-crash was observed during system suspend/resume.
In order to reproduce the issue all is needed is to call the following command,
tap the screen to wake up the system and call it again
(repeat several times usually happens after the two or three iterations)
$ echo mem > /sys/power/state
