I have a Dell Inspiron 15 laptop (Intel Core i3-6006U) running Ubuntu
17.10. Kernel 22.214.171.124 hibernates and resumes without problems, but the
three more recent kernels (126.96.36.199, 188.8.131.52 and 184.108.40.206) 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:
