Hi,
I am using hikey970 board. After writing “mem” device goes to suspend state properly within few seconds.
But Once i press power button (on the board) it takes more time(~45 secs) to resume, and i don’t see any log on the console except this “NOTICE: [set_ics_power_up] done!”.
I don’t see logs related to resume also, unable to debug why it is taking more time to resume.
Any suggestions?

hikey970:/ # echo mem > /sys/power/state
