After solving the conflicts, I applied the revert (see attachment) to v3.18.7. I think it should also apply to the current head. With that patch, suspend is working again on that version.
However, I have not to deep knowledge of that subsystem, so please, someone who have, have a deeper look into it. I especially do not know if the lines in .../intel_pm.c are correct or better leaving them as they are in v3.18.7.
I want to have it working on a version that I know is stable before asking to pull it to head.
Hi Klaus, we fear this patch may hide the actual cause. Would be useful to get a better description of what happens, along with a dmesg with drm.debug=14 module parameter set. This might clutter the mailing list, would you mind filing a bug at [1] and attach the info there?
Thanks, Jani.
