I have the same problem, using the 16.04 Ubuntu release build, with latest updates. Kernel is 4.4.0-21-generic AMD64. Dell XPS13 9350, with 1.0.4 firmware, Intel i5-6200U, 4GB RAM, 6GB Swap.
Suspend/Resume works fine. The hibernate seems to stop towards the end of the process, just before it powers down. Screen is blank, keyboard backlight goes out, etc. It doesn't get over that final hurdle. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1562093 Title: [Dell Inc.
