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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1857883 Title: system failed to suspend To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1857883/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
