Now I think the problem is not in kernel. The error is same at Tumbleweed with
kernel from Leap 15.1. Full system Leap 15.1 works OK (boot from instalation
flash). See my previous message (2019-09-01 10:18:14 UTC). I do not know what
komponent can make problem (udev, systemd ?) and if downgrade of that komponent
is harmless for my system.
