GPU hangs after resume from suspend

[Reinis Zumbergs]

1) Xenial 64 bit
2) linux-headers-generic 4.4.0.10.11
3) Graphics hardware acceleration should still work after resume from suspend
4) Chrome gets frozen, glxgears does not work, games do not launch etc.

Reinis Zumbergs, 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.

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

Thank you for your understanding.

I'll try.
Problem is that it's not happening every time. If I suspend and resume a moment later, it usually still works.
And I cannot just run on the newest kernel all the time, because it's my main work machine and I need Virtualbox guests to work.
Stand by :)

[Reinis Zumbergs (reinis-zumbergs)]

Ah, of course, I have to install the corresponding headers too, so that DKMS module gets built. Now I'll run daily on the latest kernel, that will increase the testability.

Additional symptom to the bug report. Sometimes instead of freezeing, GPU accelerated windows get kinda disturbed - flickering and artefacts on screen.

I have been running linux-image-4.6.0-040600rc6-generic for two weeks now. And have not experienced a GPU hang since.

[penalvch (penalvch)]

Renis Zumbergs, the next step is to fully reverse commit bisect from kernel 4.4 to 4.6-rc6 in order to identify the last bad commit, followed immediately by the first good one. Once this good commit has been identified, it may be reviewed for backporting. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

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

After the fix commit (not kernel version) has been identified, then please mark this report Status Confirmed.

Thank you for your understanding.
