ramon, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

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, Y, and Z are numbers corresponding to the kernel version.

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.

Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Tested and confirmed under Linux 4.3.0-040300rc1-generic

ramon, could you please provide the missing information following https://wiki.ubuntu.com/DebuggingKernelSuspend ?

[ramon (agmonr)]

working according to:

[Alberto Salvia Novella (es20490446e)]

Please:

1. Report to <http://bugzilla.kernel.org/>.
2. Paste the new report URL here.
3. Set this bug status back to "confirmed".

Thank you.

ramon, unfortunately bugzilla is the wrong venue for this issue. Also, as this report doesn't have enough information yet, it's not yet ready to upstream at this point.

Despite this, the next step is to fully commit bisect from kernel 4.1 to 4.2 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit bisecting.

Thank you for your understanding.

Hi, Christopher.

I tested the bug with:
kernel linux 4.3.0-040300rc1-generic and it has the problem.
kernel linux 3.19.8-031908 doesn't have the problem.

10x.
