Comment # 18 on bug 104825 from Harry Wentland

Thanks for your bug report, and constant testing and feedback. Since the
original issue is fixed in drm-next-4.17-wip I'll mark this resolved. If I'm
jumping the gun here and you still notice problems feel free to reopen.

The suspend/resume issue you mention seems to be something else and might be
best tracked with a new bug report, possibly on kernel.org as I don't see an
indication that this is graphics driver related.

As for back-porting the changes, AFAIK this bug report uncovered quite a few
issues which were all fixed with separate commits. I don't think all of them
have been pulled into 4.16.
