@Paul: Many thx for tracking this down. I didn't try to revert the
patch, but my XPS 13 (9360) enters and resumes properly from
suspend-to-ram after running "echo deep | sudo tee /sys/power/mem_sleep"
(#sigh, I should have thought of this myself earlier, as I had seen that
commit :-/ )

@Mario: many thx for the detailed mail you just send to explain things.
Looking forward to give supend-to-idle (which Windows uses on this
laptop) a try. If you need help with testing anything let me know, if I
can spare a minute I'll try to help.

Ciao, Thorsten
