Comment 10 for bug 719620

We still have then the video blank on resume issue. I cherry-picked some more fixes from drm-intel, and built a new test kernel, can you install it and check? (it's on same url as before)

It's a shot in the dark, but the fixes may be can help here. Also can you get dmesg over network (eg. ssh into it) from the system after it resumes and attach here? May be there is something in it which can point at what's happening.
