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.
