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 have the same issue. I've filed a bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1774150 – donnek May 30 '18 at 08:42
  • @donnek - have you been able to arrive at any solution?

    As for myself, I have reverted to 147 and pinned this kernel version so that my system no longer updates to a newer kernel version, and now everything is working fine.

    Anyway in the coming months I will have to abandon 14.04 as this is the last year it will be supported, so didn't scratch my head much trying to resolve this issue.

  • After downgrading intel-microcode from 3.20180425.1 (trusty-security update) to previous version 2.20140122.1, wakeup after suspend finally works again for me... – BS. Jun 14 '18 at 17:53
  • To revert I used synaptic and its "force version" option in the package menu after searching/selecting the intel-microcode package (plus the option to block version against update after that). The hardest part for me was to obtain a precisely timed list of updates to sort the (few) possibly bad ones. – BS. Jun 27 '18 at 13:47
  • I tried just updating the Kernel while ignoring the intel-microcode update, and yet again I experienced the suspend/resume failure. Eventually, I have decided to continue to pin my kernel updates, as anyway, in the coming months I will have to upgrade to 18.04.

    For this particular issue, I have decided to go with the popular norm 'If it ain't broke don't fix it.'

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.
