(Get the code!)
the pre-loaded Xenial OEM image works well.
So, I tried to update the kernel on Xenial OEM, to approach the environment of Bionic.
The steps are:
1. install latest oem kernel 5.0.0-1030-oem-osp1 , then systemctl suspend and passed.
2. install latest linux-firmware 1.173.14 , then systemctl suspend <= FAILD
Please refer to following attach message by "apport-collect -p linux-firmware"
From Bionic side,
because there's no error message during dark screen (/var/log/kern.log from next boot), so I tried debugging it by pm_test on Bionic. Then this issue can be reproduced by processors sleep level.
