i.MX8MM Weston desktop can't wake up

[charleshuang]

Hi NXP,

We sleep/wake up(wake up 20 seconds, sleep 10 seconds) system continuously about 1000 times on our  i.MX8MM board. The yocto system wake up normally and also has a wake up log, but the Weston desktop sometimes does not wake up. If we re-execute the  "systemctl restart weston" command, the Weston desktop can work again. Could you please help to give some suggest? Thanks.

1. OS: 4.14.98 Yocto 2.5
2. Replication method: sleep/wake up (wakeup 20 seconds, sleep 10 seconds) system 1000 times continuously.
(1) echo mem > /sys/power/state to enter suspend
(2) trigger power BTN to wakeup system.

Bellow is the Weston log. The blue log is the normal sleep/wake up Weston.The red log is the problematic log after sleep/wake up, and it does not to be activating. Details as the attached log files.
