Hibernate stopped working after upgrading to Ubuntu 16.04.1 LTS

[Nilesh Pereira]

Hibernate has stopped working for me after upgrading from Xubuntu 14.04 LTS to Xubuntu 16.04.1 LTS. I tried Ubuntu Mate and Ubuntu Gnome, but it made no difference.

Laptop model HP G42-303DX.

lsb_release -rd
Description: Ubuntu 16.04.1 LTS
Release: 16.04

uname -a
Linux xubu 4.4.0-38-generic #57-Ubuntu SMP Tue Sep 6 15:42:33 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Expected behavior after clicking on "Hibernate" button in shutdown menu, or by running "sudo pm-hibernate" in a terminal would be for the laptop to go into hibernate mode.

Actual behavior is that when resuming after hibernation, the laptop simply restarts. This worked in Xubuntu 14.04. I have also followed the instructions to enable hibernation as per https://help.ubuntu.com/stable/ubuntu-help/power-hibernate.html.

Please let me know what additional information you require from me.

Nilesh Pereira, thank you for reporting this and helping make Ubuntu better.

In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically requested to do so.

It is most helpful that after testing of the latest upstream kernel is complete, you mark this report Status Confirmed.

Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available.

Thank you for your help.

Bug exists with latest mainline kernel 4.8.1. Updated tags.
