That's bizarre... no i915 activity at all after the resume ?! and only with HDMI? Imre, have you ever seen a log like this? any idea?

Would be strange if dmesg was really truncated like that. I doubt that if ssh still works. Armando, could you make sure that the log after resume is the full output provided by dmesg? The first dmesg attached to this bug resumes properly, HDMI display is enabled during resume and then after a 5 second delay there is a modeset disabling the display. That modeset looks like coming from user space. Is this also reproducible from an FB VT console?
First of all. Sorry about spam. This is mass update for our bugs. Sorry if you feel this annoying but with this trying to understand if bug still valid or not. If bug investigation still in progress, please ignore this and I apologize! If you think this is not anymore valid, please comment to the bug that can be closed. If you haven't tested with our latest pre-upstream tree(drm-tip), can you do that also to see if issue is valid there still and if you cannot see issue there, please comment to the bug.
Cannot reproduce anymore with the following configuration.
