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

14.04kernelsuspendupdates

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.
