Title:
  Resume from hibernate fails on latest kernels

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have a Dell Inspiron 15 laptop (Intel Core i3-6006U) running Ubuntu
  17.10. Kernel 4.13.0.21 hibernates and resumes without problems, but
  the three more recent kernels (4.13.0.25, 4.13.0.31 and 4.13.0.32)
  fail: hibernate appears to succeed, but resume stops dead part-way
  through. This happens whether I use the built-in hibernate capability
  or usw-susp, and whether my Gnome session uses xorg or Wayland.

  /var/log/kern.log doesn't seem to help much. A typical record of the failed 
attempt to resume is as follows:
  Jan 23 21:10:13 bombay kernel: [ 98.197921] Bluetooth: RFCOMM TTY layer 
initialized
  Jan 23 21:10:13 bombay kernel: [ 98.197937] Bluetooth: RFCOMM socket layer 
initialized

  Several other people have reported similar behaviour:

version of what I say there.)
