Experiencing Suspend/Resume Problem After Latest Kernel Update - Ubuntu 14.04




I am experiencing suspend/resume issues after updating my kernel to the latest versions viz. 3.13.0-149-generic. Since 2015, and until Kernel version 3.13.0-147-generic, everything was working fine. But now after the latest kernel update, whenever I suspend my Dell 5558 laptop, I am unable to resume; restarting is the only solution.



Specs:




  • Ubuntu Version: Ubuntu 14.04.5 LTS - x64

  • Kernel: 3.13.0-149-generic

  • Laptop: Dell 5558




Note: Whenever I revert to my backup copy (one that doesn't contain this update) that I've created using Timeshift everything is normal.



I've just answered a related solution to a similar issue here: https://askubuntu.com/a/1194066/356228. Found the solution why trying to setup Extended Security Maintenance (ESM) for Ubuntu 14.04.
