Are you doing something special with the connector? like removing it slowly? the HDMI HPD pin is shorter, so we'll detect HPD toggling and but will still be able to fetch a valid EDID.

What a coincidence, I found this bug on a forgotten tab and did some testing :) So yes, pulling the plug slightly slower indeed does that.. never noticed it before. Dunno if there's anything to be done then.
Heh. Thanks for the info. We could wait a bit before doing detection on unplug. I'll leave the bug open.
We seem to already have one enhancement request opened about it. Closing as duplicate. *** This bug has been marked as a duplicate of bug 76464 ***
