  No successful resume from hibernate beyond kernel version 4.13.0-21

Status in linux package in Ubuntu:

Bug description:
  I used hibernate (with uswsusp) in 17.10 successfully until kernel
  4.13.0-21. I cannot resume any more with kernels 25 or 32. I can see
  that suspend works fine, resuming the system works fine too (reading
  the image is successful according to uswsusp output) until the point
  where GDM should come up but the screen just stays black. I tried
  reaching the machine via SSH but it's not reachable.

  Tested on Lenovo T560 and T530 without discrete graphics.
