Comment 29 for bug 1359689

After some further research, we would need to backport quite a few commits to get the fixes from v3.19-rc1 into utopic. It would probably be too many changes for a stable release. At this point, the following commits would be needed, just to get abd69c5 to apply:

144ecb9 drm: Add atomic driver interface definitions for objects
cc4ceb4 drm: Global atomic state handling
2f324b4 drm/crtc-helper: Transitional functions using atomic plane helpers
623369e drm: Atomic crtc/connector updates using crtc/plane helper interfaces
abd69c5 drm: Handle atomic state properly in kms getfoo ioctl

Vivid will get all of these commits when it is rebased to upstream 3.19.

For Utopic it may be easier to perform a bisect to find the commit that started causing this issue, that is if it is indeed a regression. Can anyone affected by this bug report that they had a prior kernel that did not exhibit this bug?
