Sorry for the too long files in this window. On my screen the seemed to be small. As i tried to show in comment #8 (attachment part of resume messages #1), I could not find any kernel-warnings during resume with kernel 3.18.X . Now I used strace in a correct way. (As I will hope.) There are 2 new attachments and I think, that there are named in a way, that you can work with. Otherwise please ask. (I am not so familiar with all this stuff. Well, learning by doing can be quiet interesting and exhausting.)
