Request: Add/backport this patch for stability with Bay Trail

[Hanno]

Hi,

please add and backport this patch to current Ubuntu kernel packages:

https://lists.freedesktop.org/archives/intel-gfx/2017-February/120021.html

It is the result of a lengthy bug hunt described in

https://bugzilla.kernel.org/show_bug.cgi?id=109051#c683

There are several bug reports of stability problems with Bay Trail devices on Launchpad where this patch should help make things better, while the search for the root cause of the problem is still going on.

[Brad Figg (brad-figg)]

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1666439

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Brad, this is a feature request that doesn't require a log. Thank you.

[Seth Forshee (sforshee)]

It doesn't look like the maintainers have accepted the patch yet, in fact there's even a newer revision.

https://lists.freedesktop.org/archives/intel-gfx/2017-February/120036.html

We need to wait for a patch to at least be applied in git so we can be reasonably sure it's the final version of the fix.

[Hanno (hzulla)]

It doesn't appear to be a newer revision, but a two-part patch.

Nevertheless, I'll leave the decision to you experts who know how to read patches better than I do.

[Seth Forshee (sforshee)]

The subject is the same, except that v2 has been changed to v3. Normally that means a new revision of the same patch. Multiple patches in the same series are typically denoted as [PATCH 1/N], [PATCH 2/N], etc.

[Hanno (hzulla)]

A new version of the patch has just been released and testers are requested:
