Title:
Resume from hibernate fails on latest kernels
Status in linux package in Ubuntu:
Incomplete
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:
