I see the miracle :) according https://01.org/blogs/rzhang/2015/best-practice-debug-linux-suspend/hibernate-issues
I try two options: 1. initcall_debug 2. echo 0 > /sys/power/pm_async Before I can reproduce the bug each time I press power button for suspend/resume (after resume I have a black screen with in 100% times when conditions described above satisfied). then I try to disable pm_async and after suspend/resume I have no this bug. BUT, after restoring pm_async value to 1 via reboot, I cannot reproduce bug anymore. It is not happen in same situation as earlier. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1849084 Title: Freeze on system-resume caused by kwin and amdgpu driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kwin/+bug/1849084/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
